The reason I ask is that there is a tree on Family Search with Mary Dormer 1809 and Jane Jewell 1811, their mother Mary is said to have died in 1823. However in 1815 there is a marriage of Richard Cater, widowed and Jane Dormer also widowed St Mary’s Portsea. Jane Jewell Cater is baptised 17/8/1823 but born 20/12/1817, father Richard Cater and Jane, another non conformist baptism I’m guessing. Jane Jewell Cater married William Lewis 9/5/1850. In 1841 Richard Cater is living in Gloucester Street Portsea, age 67 with Jane Cater 55 (?) and Margaret Jewell 80 (mother in law?)
In 1851 Richard Cater 78 head, Jane Cater 75 daughter Jane Lewis and son in law William Lewis.
The death of Mary, Richards first wife must have been well before the marriage in 1815 if he married again in 1815. Looking in Portsea, the Jewells and Dormers all seem intertwined. There is a marriage in 1804 of Jane Jewell to Isaac Dormer and I’m again guessing that this is the Jane Dormer who married Richard Cater. I’m hoping all this might lead to the ancestry hint Jane Jewell born 20/12/1815 Meeting House Alley Portsea
