In working with some recently adopted ancestral profiles, it appears to me that WikiTree may have Elizabeth (Toms) Phelps connected to an incorrect second husband in Zachariah Nixon. Her birth, first marriage and children from first marriage are documented. Husband Jonathan Phelps died 1732 so a second husband would be expected. However, marriage records for Zachariah Nixon show his wife to be Elizabeth Nicholson, not Phelps (or Toms). And, Zachariah would have been approx 14 years Elizabeth's junior (not unheard of but significant).
