Children notes
WARGS says "The number of descendants of this man is huge". (Widower Richard married again in 1726.) Apparent discrepancy: the 0200 page shows William with no birth or death years. Check that page for much more detail, particularly of the sons; but it cites very few primary sources.
Geni.com lists 11 children and says (inter alia): Susannah [whose stated birth date pushes her mother's birth date back a bit!] married Conrad Kuster and had 14 children; Dorothy married John Chalfant and had 13 children; Catherine married John Morris (with no children shown); Mary married Israel Morris (with no children shown); Elizabeth married Thomas Bull and Thomas Rossiter and had 10 children; William married Ann Adams and they had 3 children; Abraham (b1707) married Alse Adams and they had 4 children; Ann (b c1710) had 6 children with surname "Umstead"; Catherine married John Morris (with no children shown); Isaac has no spouse or children shown; Margaret married Paul Castleberry and had 6 children; Hannah has no birth or death date or spouse or children shown [so we guess her birth to be in the biggest gap].
