Sarah Norris, the mother of Katherine Baker Thornton was descended from Nicolas Norris of Hampton and Exeter, New Hampshire. Nicholas does not appear in any records until his marriage in 1663/4 to Sarah Coxe, daughter of Moses Coxe and his wife Alice. Nothing is known about his (Nicolas) parents, DOB or place of birth. There is some speculation on ancestry.com and other sources, both web and old reference books, that he was from Ireland but of English descent, but the push of Irish immigration didn't really get going until after the restoration of the monarchy in England. He was probably born around 1640. He is also said to be a tailor and a planter. It is not known when he arrived in Hampton, some sources suggest he was there by 1654.

If Nicholas was born in 1640 and died sometime after 1725, he was at least 85 when he died, a great age at that time.
