He was called to the bar in 1840 and established a law practice in Dublin. The Dublin City Directories of 1850 lists him at 10 Rutland Street. In 1864, 1878 and 1880 he was listed at 39 Summer Hill. He was a member of the Law Society of Ireland and the Solicitor's Benevolent Association.
His obituary appeared in the Belfast News-Letter of 22 October 1888 (pg. 5) as follows:
“Mr William Rice Meredith, a highly esteemed member of the solicitors’ profession, died on Saturday in Dublin. His advanced age and declining health induced him to retire some few years ago from the active practice of his profession, and his business, which was at one time considerable, devolved upon his son. He conducted in his time several cases of great public interest, notably the litigation on behalf of Rev. Mr. O’Keefe against Cardinal Cullen and Bishop Walsh. Mr. Meredith was a man esteemed for his integrity and principle, and he has left his good name as a heritage to his sons, three of whom are well known in legal circles, and one in particular as a leading member of the junior bar.”
He wrote a letter to Sir William Betham, the Ulster King of Arms, which gives an interesting insight into what the Meredith family knew about their ancestry and what they conjectured. The letter included a sketch showing that the family believed they were descended from John the brother of Richard Meredith the Bishop of Leighlin. The transcription of the letter (which has one or two illegible phrases) is as follows:
“Instructions on behalf of the Descendants of the late Ralph Meredith for making out the Pedigree of this family.
For Sir William Betham, Ulster King of Arms
William R Meredith. 31 Upper Dorset Street
Instructions for making out the Pedigree of the descendants of Ralph Meredith late of the City of Dublin Notary Public deceased.
The tradition of the family with respect to this pedigree, is, that there were 3 brothers natives of Wales, of whom one was a Bishop, another a General and the third the youngest a private Gentleman, that this youngest brother formed an imprudent match with a Miss Lamb in consequence of which he incurred the displeasure of his family and that to avoid their constant reproaches he came over to Ireland with his Lady and settled in the County of Wicklow upon the property of the Howards. The earliest record, that, indisputably, refers to their pedigree which the family have been able to discover, is the Will of Mathias Meredith, the Grandfather of said Ralph Meredith, who it appears was a farmer in the County of Wicklow in Ireland under the Howards of the lands of Templeraney and Carrisole(?), his Will was made and proved in the year 1729 in the Consistory Court of Dublin. From the contents of this orthography [--unclear--] it would seem that he was not a man of education, the only real property mentioned in it is a lease which he had of the lands of Templeraney and Carricole(?), he left 3 sons, Mathias Edward and John, the two first died without issue, the last was the father of said Ralph Meredith. From the time of Mathias down to the present, the pedigree is sufficiently known, but antecedent to Mathias, it is involved in complete obscurity. It is conjectured that the Bishop of Leighlin and Ferns who died in 1597 was one of the 3 brothers, the reasons which the family assign to this, are in the first place, that, so far as they have been able to ascertain, this gentleman was the only one of his name who was a Bishop. secondly that they have always heard that they were connected with the families of Sir Henry Meredyth and Sir Joshua Meredith who are [--unclear--] descendants of the Bishop of Leighlin and Ferns. It Must be observed however that the tradition of the family does not say that the Bishop the brother of their ancestor ever came over to Ireland. It appears that the Bishop of Leighlin and Ferns had a brother of the name of John Meredith who resided in Ireland, the Will of the latter was proved in the Consistory Court of Dublin in the year 1596. In it he expressly calls the Bishop of Leighlin & Ferns his brother, and he appoints him overseer of his Will, the Will is now so mutilated that it is very difficult to read it, but sufficient of it remains to show that this John Meredith was not possessed of much property. Two children are mentioned in the Will, John and Maria. The history of both these where they lived or died or whether or not they left any issue is involved in utter obscurity. It is conjectured however that his son John Meredith was one of the lineal ancestors of Mathias Meredith. It may not be amiss to observe here that the proving of the will of John Meredith in the Consistory Court of Dublin was not in-consistent with his having possessed property in the County of Wicklow, because the lands of Templeraney and Carricole(?) are in the Diocese of Dublin. There is no mention however of these lands in his Will, so far as it can now be said. The Will of the Bishop of Leighlin and Ferns the [unclear] have not seen, it is not improbable but it may throw some light on the history of John & Maria, his nephew and niece. Sir Wlliam Betham will have the goodness to look into this view, It appears from the Registry of the Ulster office that John Meredith brother of Bishop Meredith was buried in the burial place of the latter on the 26th of December 1596. The Register of burials in Patrick’s Cathedral has been examined but there is no entry in it of the burial of John & Maria or of any descendants of John Meredith the Bishop’s brother. It would appear that with the exception of John Meredith and Sir Amos Meredith, none of the descendants of the Bishop were buried in his burial place. [--section crossed out--] no information can be obtained from it. The Register of the Parish of Rathdrum was also destroyed at the same period. Sir William Betham will have the goodness to try and make out the pedigree and commissions of the [--unclear--] family. The adjoined sketch of their pedigrees is drawn in accordance with their conjectures as above stated.“
Subsequently, an entry appears in the Miscellaneous Search Notes of Genealogical Office Manuscript no. 815, which appears to refer to the claims made in this letter, and concludes that there is no evidence of the descent from John Meredith the Bishop of Leighlin’s brother. A partial transcription of the entry follows:
“The Pedigree of the family of Meredith was registered in Vol, XX pp. 64.65. It is undated but the fees were paid 7 June 1842. It purports to deduce the descent from John Meredith son of Robert ap Grono and brother of Richard Bishop of Leighlin. This John Meredith brother of the Bishop was buried in St Patricks Cathedral 26 Dec 1596 as appears from his Funeral Entry where his Arms are recorded:- Gules on a Chevron between three Goats heads erased [?] Or, as many trefoils of the last [?] – the same Arms as those recorded for the Bishop. From his will dated 24 Dec 1596 he appears to have had a wife named Tomasine, an only son John his executor and an only daughter Mary. Nothing further is known of these children. But according to the Pedigree, John the son is represented as the father of three sons John Edward and Thomas of St Peters Parish Dublin of whom Edward of Bow Lane (buried at St Peters 26 Dec 1696 100 years after his grandfathers death) is said to have had five wives, and by the 2nd of these Ruth who was buried at St Peters 25 Nov 1671 had two sons Matthias Thomas and Margaret [—]. It is evident from the rough draft of the Pedigree in the Office that there is no proof whatsoever that John Meredith executor of his father’s will in 1596 was ever married or left issue. . . . . . The pedigree appears to be correct from Mathias Meredith of Templerany down, but there is no evidence that Mathias was the son of Edward Meredith of Bow Lane, his name does not occur in the Register of St Peters Church. It would also seem that there were two persons named Edward Meredith in St Peters Parish.”.
