Back to James Gelling.
Liverpool 1851 St Ann Place
James Gillian Head 32 married, shoemaker b. Isle of Man
Ellen Gillian wife 27, b. Ireland
James son 2 b. Liverpool
John Gillian Lodger 23, shoemaker b. Isle of Man
Henry Beach 19, Lodger shoemaker b. Isle of Man
Charles Smith 14 Lodger shoemaker b. Ireland
Gillian is not a Manx name and it is possiby a misspelling of Gelling.
Did you find out Eliza's maiden name? Was it Smith?
Could John be a brother of James?
