I see John Twyman 1877 aged 4, with his parents on the 1881 Census at 2 Crofts Court, Margate
John aged 47 is a Hawker and Mary is aged 40 both born Margate.
Crofts Court is no longer there but I do have it clearly shown on some maps, in the Market Place of the Old Town, so John senior was probably a Fish hawker.
John and Mary also have a daughter Mary aged 7 on this census.
On the 1901 Census, John W Twyman is aged 24, married to Alice aged 20 and head of the household, with him is his widowed mother mary Ann.
John is a Labourer of 15 Florence Cottages (off High Street). Annie born Salisbury Wiltshire
John Twyman married Alice Leonard Q Dec 1889 Thanet Vol 2a Page 2136.
So, what can I help with?
