Hello fellow Ansonians,
Adeline, I might be late in the day with my post, but I just wanted to let you know that it appears that your grandfather, John George Harrison's mother was Lucy Harrison (née Anson). She was George Anson's sister. My g.g. grandfather was George Anson, so Lucy Harrison must have been my g.g.g.aunt.
It appears that your grandfather didn't change his name, however I haven't yet found out Lucy's husband's full name yet. I'm pretty certain it will be found on the 1901 census return.
If I can be of further help, please say.
(Good evening Ansonian63! :)
