A few comments:
- what's the evidence that he was born in 1706? This looks to me to be a guestimate. No baptism has been found, and as would be expected in 1751, no age was given on burial
- the burial entry is merely Thomas Conquest, labourer. There are no death records before 1837, and burials have never shown birthplace
- anything relating to the Conquest family of Cardington before 1726 is speculation. No-one knows who Thomas Conquest was, where he was from, nor who his parents were.
- there's more than one tree on Ancestry named Conquest Family Tree. Who's the owner of the one you recommend?
- I place no credibility on Ancestry trees, which are good as guides only, with details needing to be checked against original records
- the early Conquest family is fairly well documented, including a pedigree on the Visitation of Bedfordshire. The problem is establishing whether or not Thomas descends from them.
