Digging up an old post because I am seeking the same information. There is a book that lists one of George's grandsons through his son Bernard, James Gill Elrick, as a descendent of Pieter Alricks of New Amsterdam, but there don't appear to be any possible connections here. The regions seem to be correct, as Pieter lived in Delaware and much of his progeny moved up into Pennsylvania, but the dates never match up. Outside of that, I have no idea who all else might be even remotely related upstream.
