Thank you for bringing this William Lamacraft to my attention. I did not find him the last time I searched the IGI. This certainly refers to the William Lamacraft I am looking for as the childrens names and dates match. However, there are some errors on the IGI. All William's children were born in Upton Pyne rather than Broadclyst, as confirmed by the parish records. Charlotte was born in North Tawton in 1819 and was not the mother of William's three eldest children. It looks like the IGI entries may have been recorded some time in retrospect. However, I will check Broadclyst for William's birth the next time I am able to get to the parish records. If you believe this family are related to yours, I would be happy to share information.
