In addition to searching for a webpage or email address for a local genealogical or historical society, search for their Facebook page as well. While not all organizations have a Facebook page, many do. Depending upon the set of up their page, you may able to “instant message” the organization or email them via Facebook. I usually keep my first message relatively short–until I’m certain that someone is actually monitoring it and I get a response. Don’t expect instant responses as these organizations are typically staffed by volunteers or staffers with limited hours.
Interacting with a group’s Facebook page can be just another way to reach out. Keep in mind that many organizations do not have the time or the staff to perform research at no charge–especially for individuals who are not members, but communicating via a Facebook page can be a way to make contact.
