Hello... thanks for posting in G2G.
That will be fun trying to find out about that connection for you.
There are 2 things I think we need in order to make a meaningful attempt....
1. A little bit more about your grandmother (there were many Virginia Dillons). Any of the following could help: estimated year of birth or death, place of birth death or marriage, your grandfather's name, their children's names and birth places, anywhere the family might have lived, etc. Any clue could be the key.
2. A little bit about Ricky Dillon: I looked him up and found information is available. With some digging we could probably figure out who his ancestors are.
If there is a close relation such as 1st or 2nd cousins it should not be too hard to work out. If their connection (assuming we are all ultimately connected) is much further up the tree or through multiple surnames it could take quite a bit more work to identify.
You can post more information relative to the search here.
You should also consider joining WikiTree (all free and it only takes a few clicks), and make a profile for yourself, then ones for your parents and grandparents. We can all work together to figure out your ancestry. Even if there is no connection to Ricky, I assure you there is a connection to someone just as notable and fun for your family to talk about.
I hope to hear from you soon!
