Hi Dave,
Glad you had a good morning fishing.

I put a posting on the "Genealogy" section of the Belfast Forum about RIC records and received a reply from a chap called Deke in Canada.
Deke sent me the name and email address of someone who has (or had) some sort of RIC index. I sent her an email earlier this afternoon and I'm eagerly awaiting a reply.
I'll let you know the outcome. I'll try the PRONI if all else fails.
When I moved into this house 20 years ago, I could see Strangford Lough from the back bedroom, then a couple of years later they built some new houses behind us ..... no view of the Lough anymore.

Another sunny day here.
I'll keep you posted.
Best regards
Dave
