If you are referring to the Florida Pioneer Certification Program of the Florida State Genealogical Society, I would suggest you go to the web site <www.rootsweb.com/~flsgs> and contact the membership chairman. They can give you the last known mailing address of the person who obtained a certificate. If they did not keep their membership after obtaining a certificate, it could be an old one. If you are in Florida, the FSGS newsletter Florida Lines prints the membership directory - with the majority being in the first issue printed the end of March first of April and updates in each subsequent issue. These should be found in the libraries with genealogical sections and local societies. All local societies receive a copy of the newsletter and it is usually donated to the library if the library does not have a membership. I must "warn" you that it is the busy time of the year for FSGS reviewing current pioneer applications, so there may be a delay in getting a response. I would think that posting to a list like this would also be helpful for current contact information. The membership list is just within the last two years been converted to keeping track of e-mail addresses, and as everyone well knows, those are constantly changing unless notification is sent. A quick peek did not show either of these people with current memberships. Leslie
