One of the things I always try and promote—especially to younger genealogists who often think they can find everything online—is the amount of help and information that can be obtained from a local family history group or society. At the most recent meeting I attended of the Fairfax County Genealogical Society Irish Special Interest Group (in Virginia), I learned a number of interesting tidbits about Irish genealogy in as far flung places as Washington, D.C., New Zealand, and St. Paul, Minnesota.
While their website could do with an update (there is a notice saying it is under construction), FIR has a number of items of interest on there:
An indexing project that will compile all names found on headstones in St. Mary's Cemetery, Brockton, MA. This database is listed as 'coming soon' on their website.
A mention about their library of over 5000 publications.
Videos (downlandable files) of lectures concerning different Irish genealogy topics.
A list of publications you can read by FIR members, mostly about Irish, U.S., and Canadian genealogy topics.
So, if you live in the area, or are visiting, get yourself down to one of their Friday evening meetings!
P.S. This group is included in the Groups/Societies & Institutions section of this website. On this page you can find the details for many Irish family history organizations and institutions that have a large number of records relevant to Irish genealogy.
