I have a wealth of information on the lineage of Joanne O'donoghue and John Adams. He was my great great grandfather.
My email is jadams7793@aol.
I'm looking at an old family tree, hand written that goes back to Joseph Adams. He came to Dingle from Wales in 1777 and married Anne Hayes. he was in the British royal navy and sailed with Capt James Cook. He had five children. Mary, Margret, Thomas, Samuel, and John. One of them parented your John, but it unclear which one. I may have some connection in my records and will try and find it. John had 9 children. One of them, Thomas married Margret Curran. But they only have 4 daughters listed, son John. However, Thomas had a brother John who was a Doctor who immigrated to Springfield. he still has children in thei area. He came to my sister wedding many years ago. Anyway, if you send me your e-mail address, we can start exchanging information. I have a lot of the connections you're looking for and hopefully you have some that I need.
