We would love to help you find out about her ancestry.
The best, easiest, and most effective way would be for you to join WikiTree (it only takes a moment and is free), then you start with just a few basics such as your profile, your husband's, then her's. Anything else you add will help such as her husband, any other children, any places you might know or dates. The ones you don't, don't worry... we just start from where we are able. Then we work together to connect her branches to the world-wide tree.
We could work together on your tree too!
You should contact me if you have any trouble logging onto WikiTree (but I can't imagine you will),
