there is a William Towerton married to a Maria Trendell
10 Jul 1845 All Souls,St Marylebone,London,England
but that would not tie in with his birth date.
This William was born (c) 1817 to a John Towerton
There is a marriage on Ancestry a copy of the marriage register, if this is the right person
to confuse issue there is a William Towerton 04 Sep 1853 ELLESBOROUGH,BUCKINGHAM,ENGLAND to a Daniel and Ann
Can i ask where have you got the info for William 1853 is it on a census?
