Parents of Mary Langstaff m. Samuel Potter

I'm trying to determine who are the parents of Mary Langstaff (1671-?) married to Samuel Potter (1671-1756). I have their children born between 1691 and 1708 so her birthdate of 1671 seems about right. I've seen two sets of parents claimed as hers so I'm trying to figure out which is correct.

The first I've seen is Henry Langstaff (1645-1718) and his wife Sarah. He's the son of Henry Langstaff Sr. (1605-1705) and his first wife Josephine Knight.

The second is Henry's half-brother John (1638-1707) and his wife Martha Martin. John's parents are Henry Langstaff Sr. and his second wife Elizabeth Collins. I've seen a daughter called Mary, but her birthyear is 1689 which would be too late for my Mary Langstaff.

Does anyone know which is correct?
