It does go back a bit further, if correct.
Alice Croasdale was the daughter of John Croasdale, 1800-1856 in Liverpool, and Margaret Williams, 1817-1884 in Liverpool.
Then William Croasdale, b 1772, no wife listed, and Edward Williams and Elizabeth Hughes, but no details.
There is a William Croasdale baptised on 20th January 1771, in Tatham Fell, diocese of Blackburn, son of William of Ballshaw.
I think Barbara's husband was born in 1943, so possibly still living.
