I’m want see lineage ya

I seem to be stuck at around 1750. There does not seem to be a record before this of my line. I have spoken with many researchers from other lines of the same name, they claim that my name comes from Peveral (the surname of William the Conqueror). According to these researchers, one of my distant relatives is supposed to have been his son that gave up his title to marry a common woman.
