Hallo Tony,
I have come to this rather late. Joseph Tucker is my direct ancestor. His second wife was Mrs Mary Ann Cummons (nee Wright) who had 3 sons (and a daughter, Mary Ann?) by her first husband, John, who were called William, John and Richard. In one census, the 3 boys call themselves Tucker, but in fact they were Cummons, or Cummins.
Joseph had a son from his first marriage, also Joseph, born 1828 in Bristol, but I don't know what his first wife was called.
By his second wife Mary Ann Cummons, Joseph had Benjamin, born 1840 (my ancestor) and Jane Elizabeth born 1846, who was living with her half brother John Cummins in 1861.
Mary Ann died on 22 January 1857, aged 56, at 13 Thornton Street, Walworth
I have Joseph Tucker as born in 1789 in St Stephen-in-Brannel, Cornwall, and dying in St Saviour's Union Workhouse in Southwark in 1871, but I would dearly love to have some corroboration of this.
Joseph was a carpenter journeyman, like his son Benjamin, who died on 29 November 1925, at 46 Ouseley Road, Balham
