Hi ,
No she should reply here on this site and then if the two of you find that you have the same family in common,you can then personal message each other.
It's always good to get some info on the boards as it could help others in the future(like the fact that you have found Florence's name here today

)
Email addresses are not allowed here in public as they could easily be scammed,so we only use personal messages to exchange private stuff or info about living people.
