Very interesting stuff, and some wonderful stories!! What heritage some of you have.
I got into it about 14 years ago, but yes, cost a few $$. I had exhausted the free resources.

Have rellies who came out from Tipperary, and from Roscommon in Ireland. Grandmother came from Kent in England, and got birth certificates from her parents. $$$$
Tried to follow up on my GGgrandfather Gleeson in Tipperary and had paid $$ for info, but there wernt many records. The guy doing the research said that the info they found was not 100% accurate anyway.
Things may have changed and improved over the years.
Good fun, and yes, a wee bit addictive.
