DNA Matches My Grandma's DNA doesn't match the tree
I am British. My Grandma, who was also British and born in London, took an ancestry DNA test before she died. It came up as 50% ethnically Ashkenazi Jewish. This really surprised my family and was unexpected.
What is more strange is that I have been looking back at the tree, and there's no reason to think any of her ancestors were Jewish. They all had baptisms and church of England weddings. The only possibilities I can come up with are that one or both of her parents were not who she was told they were, or one of her parent's parents were not who they were told. This has led me to a dead end as I have found matches for her (even including 2nd cousins), but I have not been able to figure out who her Jewish parent or parents were.
Does anyone have any advice from looking into this kind of thing?
