Hargreaves and Abraham's parents are John Broadley and Ellen Hargreaves. John died of consumption 3 nov 1826. He was born 23 jun 1791, bap 17 jul at Altham, son of Abraham Broadley and Mary Pilkington. The key to this branch of the family is a will by John Broadley, bap 24 nov 1728 Church Kirk, possibly murdered his first wife, (look for Ellen Strange) died 27 jun 1813 Bell Lane, buried Altham 30 jun 1813 age 86. There are 2 Abrahams at Altham, one with a shorter run of children. Abraham 8 may 1737-4 dec 1826 (age given at death is wrong because his second wife was younger) is the brother of John, 1728-1813 and the other Abraham, with the longer run of children, is son of the first Abraham. The will makes it all clear.
So John 1791 is son of Abraham c 1761 son of Abraham 1737 son of John 1700-68 (and Marjery Briggs), son of John Broadley 1760-1733 (and Alice Grimshaw) son of Abraham and Ellen Broadley who turned up in Over Darwen near Blackburn by 1654 from where?
Your ancestor,John 1700-1768 was the youngest son, and after his father's death, he seems to have become a Presbyterian. He went to live with his oldest brother Abraham, who was a Catholic and lived at Black Lane Head. Abraham and John appear in the Dunkenhalgh accounts working together, cb
