I am a descendant of Abraham Crabs and Thankful Austin.
At this point, Philip Heinrich Krebs is as far as people have been able to research - he came from Germany on the ship Peggy on 24 Sept 1753. Unfortunately, the trail goes cold from there but with new info coming forward on a daily basis, perhaps someone will be able to figure out what town he came from. Some trees have erroneously attached Philip to Johann Krebs and Barbara Krim - they are not Philip Heinrich's parents - the wills of both parents bear this out.
There have been a few trees which say Abraham Crabs married a Thankful Lyons but no one has provided some sort of documentation to that effect as of yet. However, my 3rd great grandmother who was Thankful's youngest surviving daughter left family bible records that state her mother's last name was Austin. David Crabs the oldest child of Thankful and Abraham, named a son Austin Crabs, which seems to bear out that the last name of Thankful was indeed Austin. As of yet, I have found no one who had Lyons as their middle name (as was the practice at the time).
Would love to know your tie into the Crabs line, which son are you a descendant from - I am glad to meet another cousin!
