SUMMARY: It is believe that the reason for "Lancas" being listed as his birthplace on William's baptism and endowment record is because of his marriage license found in Lancashire. The archive sheet (FHL#1274706) had the 1877 baptism/endowment dates and his age was listed as 21 (1730), see source for marriage.
