I have found Janet and family on 1871 census living Barrack Street Onchan. David, Head aged 67 Ag Labourer born Scotland, Janet, wife aged 51 Scotland, David 22, James 18, Thomas13, Mary 11 (all Born Isle of Man). Noticed they had another son Robert born c1840 living in Liverpool. Could Mary therefore be William Moores Mother? No other daughter mentioned but possibility one had already moved away?
Will see what else I can find.
