Another brick wall (since I had such enthusiastic responses last time I posted

). Looking for verification of parents, and hopefully grandparents for this man:
William Ward, b. 3 Apr 1797 Salesbury/Wilpshire, Lancashire (baptism record at St. Mary the Virgin, Blackburn); son of William Ward and Jane
He married Betty Thwaites (daughter of Daniel Thwaites and Betty Duckworth Thwaites) on 10 Oct 1839 at St. Mary the Virgin, Blackburn:
William Ward - full age, veternary, bachelor of Blackburn
Betty Thwaites - full age spinster of Blackburn
Groom's Father: William Ward, Manufacturer
Bride's father: Daniel Thwaites, Brewer
Witnesses: Thomas Thwaites (her brother) and Jim Wilkinson (no idea who he is)
This couple had four children, the eldest being William Ward born 18 oct 1840 in Blackburn (baptism, everything checks out); no problems there. But going backwards:
Looking for the
father of William Ward the vet. He was William Ward married to Jane. I've focused on Mellor, since it's the nearest village to Salesbury and Wilpshire, and there are many Wards living there, many named William. (I also like Mellor since it's where the grandson William Ward died in 1919; possibly a family home?) If the location is correct, I found a marriage 14 Jun 1789 of a William Ward and Jane Lund, but it was in Blackburn at St. Mary the Virgin (possible - it's nearby; plus, see below).
Also found a burial of a 2 year old child at this same church, Edmund Ward, son of William Ward of Wilpshire on 20 Mar 1793 (b. 1790). A second child was baptised, same church, 2 Oct 1793 (b. 20 Sep 1793) to William and Jane Ward of Wilpshire, and he was named Edmund also (understandable since they'd just lost their first child a few months earlier of the same name).
William Ward, baptised 3 May 1797, same church, son of William Ward and Jane of Wilpshire
Jane Ward, baptised 21 May 1806, same church, daughter of William Ward and Jane of Wilpshire
This family works nicely. But I haven't been able to pin down the parents of either William Ward of Wilpshire or his wife Jane (maybe Lund - can't find a Jane Lund the right age in that area).
Thoughts?

Many thanks,
