Suzanne,
I checked various records for KILMARTIN and the following is what I found.
1821 Census:
Peter Kilmartin, age 32. [born c. 1789].
Peggy Kilmartin (wife), age 45. [born c. 1776].
(There are a number of inaccuracies in this census).
******************
Catholic Parish Registers, Baptisms 1874 - 1881:
May 23, 1880: Winifred Kilmartin.
Parents: Bryan Kilmartin & Winifred O'Donnell.
Sponsors: Martin Flaherty & Ellen Flaherty.-
******************
1901 Census:
Bryan Kilmartin, age 45
Winifred, 49, wife
Patrick, 20, son
Ellen, 15, daughter
Delia, 14, daughter
Martin, 13, son
Stephen, 10, son
Josephine, 5, daughter
****************
1911 Census:
Bryan Kilmartin, age 57
Winifred, 55, wife
Martin, 22, son
Josephine, 15, daughter
[The ages of Bryan & Winifred don't correspond with 1901 census]
More info here:
In 1911 Bryan & Winifred had been 40 years married.
They had 14 children born alive, 10 of which were still alive.
******************
I do know there was another son, Bernard (Bernie), who had probably immigrated by 1901.
I do know he was in the US. He married a Mary Anne Fitzpatrick. They are both deceased.
Their children: Patrick, Michael (deceased), Stephen ( he owns the bar in Kilronan), Thomas, Mary, Gerald, Bernard (deceased), Winifred, Joseph.
Stephen and Gerald live on the island. Patrick in Galway. Thomas in Dublin. Mary in England. Winifred in Roscommon. Joseph in US.
This is the only Kilmartin family on the island. If I get any more info, I will send it to you.
I will see what I can find on O'Donnell.
Hope this is of some help.
Mary Anne
