Robert Mallet (1761–1804), of Dublin
Robert Mallet (Senior) moved from England to Dublin and set up as a cabinet maker at 62 Capel St. He married Anne, daughter of William Pike, who had a plumbing business in Dublin. On Pike's death Robert Sr. appears to have taken over part of his father-in-law's business. His nephew, John Mallet, moved from Devon to join him, and married his daughter Thomasina. John was also joined by his father (Richard Mallet) and other family members. Richard Mallet set up business as an ironmonger at 90–91 Marlborough St., along with his other son, William. John took over the business on his uncle's death (1804), moving to premises at 7–9 Ryder's Row.
Robert Mallet (1810–81) was born 3 June 1810 in Ryder's Row, Dublin, eldest child and only son among three children of John Mallet (1780–1868), plumber, hydraulic-engine maker, and iron founder, and his wife and first cousin Thomasina Mallet (d. 1861).
