@ Have another date for you, Barbara. From the BT's (Bishop's Transcripts). Burial 29 November 1826, 78y, Ludborough, Lincoln, England, for Ruth WHITE. If her age is correct that would make her born about 1748, or about 10 years before William, married 1780 in Belchford, Horncastle District, just 10 miles south of Ludborough and 8 miles southwest of South Cockerington, Lincolnshire.
All the best. Jean (Crosskill) Rhiness.
