We should not assume that our ancestors three or four hundred years ago were Christians. Yes they may have their names in church records, Christian marriage records, etc. but this does not mean they were not Jewish. Nor am I trying to say they weren’t Christians. They could easily have been Jewish and were either hiding it or in the process of converting. There are many Old Testament names resting upon the graves of our Christian ancestors. If you can’t find any ancestry past that headstone, you should try looking at it from another angle.
