Boy do we have to be careful. I come from another Acord line, so far not connected to yours and my John who married Rachel Combs was also born in Pa about 1766 also. There is a Conrad Eckert who had a son John b Oct. 13 1766, that is not my John and I don't believe your John. This John m Catherine Elizabeth Haag/Haak. This John remained in Pa and John and Elizabeth's children are: Jacob, William, Mary, John D., Sarah, Benjamin, Isaac, Catherine and Rebecca. Thought I could save you some time in looking at Conrad's John.
