Magdalene Meyer is, by my current understanding of the facts, the second child of Captain William Meyer (TN’s William Myers Sr). Looking at various Ancestry trees and using them as a primary source, you get a birth date and birth location of Nov 1, 1862 and Hilltown Township, Bucks County, Pennsylvania. If these facts are correct, then Lt John Moyer of the Sugarloaf Massacre is likely born in Bucks as well.
She has a daughter Elizabeth around 1780, and her husband (married ~ 1777), George Jacob Kocher, is said to have died on 17 September, 1780, six days after the massacre. The way the name is given is important. George is not a first name but a spiritual name. His first name is actually Jacob. This same source gives a birthdate for Jacob Kocher of 15 July, 1756 in Hilltown, Bucks, PA. Interestingly, same source creates a chimera birth of Maria Magdelene (Polly) Kocher 01 Nov 1762, in Hilltown, Bucks, PA. Interesting that his wife and his sister are born on the same day and in the same township, and die in the same year. One is almost certainly incorrect. At this point I wonder if data for the sister was transferred to the wife.
The death location for /Jacob/ Kocher is also different, depending on source. One gives Valley, Armstrong, PA and the other is the Nescopeck I’ve heard. It’s important to know that Indian/Tory attacks were happening all over the place in this time frame, so I don’t have the facts to eliminate either possibility at this time.
Magdelena has two children, Elizabeth and George. George goes on to marry John Myers’s only daughter. Elizabeth marries Barnabas Gable in 18 Dec 1795 in Greene County, which puts another stake in the ground of the Myers clan move into Tennessee. Elizabeth is sometimes said to be born in Lancaster County, which I find a little confusing. I would have thought Magdalene + Jacob would have remained in Northampton. If it is true that this family was in Lancaster County at this time, then Mr Kocher likely would have been a part of the Lancaster militia, and not part of the John Myers rescue effort mounted by John’s father.
