Have you tried getting in touch with the local online and printed newspapers yet? The County Down Spectator
and Belfast Live
are the biggest news outlets in the area, and they both have Facebook
pages as well. Hopefully they will be able to point you in the right direction!
In addition, you could also try to locate them via Ireland Reaching Out, where great volunteers attempt to connect Irish descendants to their roots, through reverse genealogical research.
Keep us posted on your findings, and if there's anything else you need, just give us a shout.
Wishing you the best of luck on your search,
