Hi
It is quite difficult looking for records this early.
There are a few sites that are helpful in looking for older records -
www.irishgenealogy.ie -
a lot of older church records on this site I checked it out for
Thomas Sands there are a few listed but the dates don't tie in. I also looked for any
Ann Rebecca and only one baptism for an Ann Rebecca Dooley. This won't help as you don't
know Ann Rebecca's maiden name. Church records are constantly being added to this site so
it is worth checking them from time to time to see if Thomas shows up in the future. This site
is sponsored by the Irish Government.
www.igp-web.com/archives This is a very useful site with lots of records submitted by volunteers
I had a look no marriages for Thomas and Ann R.
Nick Reddan has a very useful newspaper index site just enter nick reddan's newspaper index in google search and it's the first site that pops up. I also looked at this and while there are some
entries for "Sands" none for the marriage of Thomas and Ann R.
Also a paying site which I reluctantly mention
www.rootsireland.ie I had a look at that also and while there were 25 marriages for Thomas Sands only one in Dublin and I entered the year 1810 with 10 years either side and no marriage for him in that time frame.
I also had a look at the Rosemary Ffolliot newspaper index which is held at the Cork City library and
again no luck for Thomas. Generally it was the gentry who placed announcements in the newspapers.
What about his army record held at Kew, in London. His marriage details would be held in his
record. However you do need to have his service number.
Other than the above I can't think of any other sources at the moment that might help you.
