I've been going back over my files and paperwork trying to see if I've missed anything that was important.
In doing so I noticed that I may not have confirmed with you that I received the photocopies you sent, although I realize I may have done this direct to your email.
Just in case I hadn't, I thought I'd get this off to you so that you'd be aware they were received and your efforts were very much appreciated.
I haven't found much on the Ryan's on the Irish side but have had more success with the Australian records. I found an entry for the death of a Martin Ryan in "Nenagh" -25 June 1845, but not sure if this is our Martin? Oh well the search continues.
