Abraham was a witness at Isaac's marriage in 1826.
There was also an Abraham witness on this marriage, maybe Abraham was the father
22 Nov 1818 St James, Haslingden, Lancashire, England
James Pilling - This Chapelry
Susanna Haworth - (X), This Chapelry
Witness: Nathan Sutcliffe; Abraham Pilling
Have you followed through the possible Joseph who was witness to Abrahams wedding. He married Mary Dearden in 1836 as posted by heatherjulie. It looks as though he remarried at St James in 1840 at St James, Haslingden as in 1841 his son by first marriage is with him - I wonder who his father was on the marriage and whether it would give anymore clues.
