Many thanks for your reply and as I cannot readily see a John Arthur Adams line could you kindly give me a few more details. I also do not understand what you mean by suggesting two 1841 Census entries when I only have one as below
1841 Census - 6th June
H. O. 107 - 412 - 2, Folio 99, Page 13, Line 1
Portsea Island, Portsmouth Town, Parish of Portsmouth
The White Hart, Broad Street, Portsmouth, Hants
Thomas Adams 40 Head, Publican Not born in the county
Harriet Adams * 30 Wife Born in the county
John Adams 2 Son Born in the county
Susan Adams 15 Female Servant Born in the county
As regards Susan Adams I do not know if she is related to the family or not, can you verify this.
I shall be away for the next month and so any reply from me will be in February.
