We consider ouselves lucky to have come across this board, and I have just finished reading all 18 pages, and links. We have only recently ventured into Eng/Sct research, and really not into Irish before this week. Although things could look alarming, maybe not (?) But if so many apparently in England who have Irish ancestors are lost . . .
To keep it
very brief, we have just found one ancestor, otained by looking sideways at possible friends and relatives in Sct, whose death certificate said he, George TAIT, died in 1855 in Maybole [Ayrshire Scotland] age 99 born in Stradown [Stradone ?] County Cavan, wife Mary SMITH, had lived in Maybole 25 years, some detail of 10 children born in Ireland, and his parents John and Euphemia ARMSTRONG. George' children John & Mary (spouses Susannah nee LANG and Thomas) also moved to Maybole where all their children were born, and the younger John's dau emigrated to Australia in 1858 where she married Robert HARVIE from Sct, nationality also Irish,
17 days after he arrived in 1864 - suggesting the families originally came from the same locality in Ireland.
We were/are hoping to find more detail of TAIT ancestry, but more particularly of the LANGs and/or SMITHs,
but most particularly of the HARVIE family ie, the direct line.
Being not only new to Irish research, but also located in South Australia, we really don't know what to do next.

We have put a posting on for County Cavan, Ireland - General, which you
may care to look at, but have not (yet) received any response(s).

[ps - somehow I managed to post the entry to County Cavan right at start of typing and by the time "modified", it already had 9 hits who may never look at it again.]
