There are many Lafayettes throughout the country. I work in Lafayette, California. I don't know her, but if she lives in Lafayette, CA, you could email me her last name, and possibly her address or street, and I might just be able to locate her for you.

In this country Lafayette was a much beloved person from our national history, and I'd venture to say, there is a Lafayette in EVERY state, and most counties in each state....that means thousands of them....it is an incredibly common name here in the states.
If you know her full name...given and surname...and, even better, the name of her husband, then you can take that information and go to any one of the internet white pages, fill in her name, Lafayette, without the name of the state, and see what comes up.....ditto for Jack.....maybe you'll recognize something, like the telephone #. Start here, but there are others;

Don't forget to try other possibilities....Jack is a Nickname for John, so try that, too...also, just an initial J. for given name.
Good luck.

I found her :) Thank you for the replies. After many hours on the net, I was able to locate her. We had a wonderful talk. For some reason I was not getting her emails.
