Hi Garvary:
There are two “Tattinbarr” place names. The first is where you originally had it placed, in the area in which we are most interested, being east of Maguiresbridge and just north of Knocks. The second one is a little south of Rosslea, near the border, as you pointed out.
I came across a record (using Google chrome) for:
Thomas Kenny, born Aughavin, Fermanagh. He served in the Royal Artillery, and was discharged at age 36. His military record covers the period 1796 to 1814, a period of 18 years. I assume he joined at age 18, which would make his birth year 1778, and one year older than Alice.
I could not find “Aughavin” at first try, but will give it another go. There was no other information on line, but I feel this is certainly another line of inquiry worth pursuing.
Thanks again,
Don.
