I found this quite interesting:- Mary THURLBY ofSam and MarySURFEET Lincs1795 Sarah THURLBY ofSam and MarySURFLEET Lincs1799 SamTHURLBYofSam and Mary SURFLEET Lincs1806 Edward THORLBY of Sam and MarySURFLEET Lincs1809
as I cannot find a bap. of an Edward THURLBY 1809 in the area, I would think this was a transcription error !!!
