Most of the dates are confirmed by a Biggerstaff family Bible that my cousin has.
A fun side note, if the professional genealogists are to be believed, through Henrietta Moore Biggerstaff we can trace our ancestry to a lot of European Royalty before 1377. Edward III died 1377 and he's the last.
For you newbies, A WARNING, genealogy is worse than peanuts or potato chips. There is always one more name to chase down. You'll get frustrated to the point of throwing things, but it's such fun.
