Moll was considerably older than 17-23 in 1763 when he moved from Rockland to Allentown, as he is noted on neighboring warrant surveys ca. 1750/51 (of which I have copies coming from Harrisburg). This means he had to be at least 30, if not older, in 1763, and around 40 when he married Lydia Rinker - this assumes the same man, but given the first-hand information timeline, it possibly is a father/son situation. I doubt it, but the possibility is very real. The hypothetical scenario w/ Abraham Rinker and the likelihood of a move to Northampton for $$$ reasons is a VERY very good hypothesis, and probably accurate as the timing is almost too coincidental to be coincidence.
I would be very curious to know where Kastens retrieved the information regarding Moll - directly via the archives or indirectly via later 'Histories.' Likewise with Brent Moll - I exchanged quite a few emails with him 4-5 years ago, and I don't believe that he mentioned direct archival research (all of the Northampton Co. paperwork is now microfilmed/microfiched at HSP in Philadephia and very easily accessible) but rather that most of his information on John Moll (this was the only Moll we were discussing) was coming from the 'Histories' as well as Heffner's little book. That was my impression, anyway. This is particularly relevant as pertaining to the William Moll story, for to my knowledge, no archival researcher - neither Heffner, myself nor others who have gone through the archives in both Easton as well as HSP - has ever found any paperwork relating to such an individual. Heffner goes so far as to specifically note this. This does not mean he did not exist, but it casts the story in doubt until something concrete materializes. I don't think this doubt implies that later descendants were being deceptive in any way, as obviously there would be no reason to invent such as story. However, 19th century genaeology based upon oral histories is tenuous at best. If such paperwork exists I would love to know where it may be found, as perhaps it may shed additional information on Johannes Moll's origins.
As it now stands, since we know he appeared in Rockland ca. 1750-1751, I am tentatively planning another trip down to HSP to research Philadelphia Co. records (this being what the area was designated at the time) or possibly I may shell out some $$$, use a local pro and save the gas money, given what it costs at the moment!!!!!!
