I have been able to trace my family from Betty Becca Kelsall's marriage to Jonas Wilson Glenton in 1787 in Liverpool. Her father was James Kelsall but I have not been able to assign him to other documented families of Kelsalls in Liverpool. Searches for "James Kelsall" on Ancestry and in Trade Directories can be summarised:
1743 Marriage of James Kelsall to Margaret Wilkinson, All Saints
1745 Baptism of Wilkinson Kelsell son of James Kelsell, St George
1748 Baptism of Sarah Kelsal daughter of James Kelsal, St George
1750 Marriage of James Kelsall, husbandman to Margaret Sherwood, St George
1756 Baptism of Colonell son of James Kelsall, Land Surveyor, Martindale’s Hill, St Nicholas
1763 Baptism of John Kelsall son of James Kelsall, Land Surveyor, St Peter
1764 Baptism of Betty Beccah Kelsall daugter of james Kelsall, Land Surveyor, St Peter
1773 Gore’s Directory for Liverpool:

Kelsall Richard, attorney, 2, ditto. Office, 11, Prince's st., Dale st.

1787 Marriage of Betty Becca Kelsall to Jonas Wilson Glenton, Merchant of Derby Square.
Witnesses: Sarah Kelsall, Margaret Glenton, Robt ????, Richd Kelsall
I think that there are cases to be made for and against a connection with Richard Kelsall (d.1749) and Sarah King d.1766? Any comments would be appreciated.
