Hello - I'm also descended from this family (hi, Ruth!). Here's what I've found so far:
James Matymore and Anne Gilbane married in Kiltoghert parish on April 20, 1846. On later records, their married last name is usually Mattimoe/Matimo/Matinmore, etc. On their children's baptism records, Anne's maiden name is spelled with a K instead of a G.
In 1853, James & "the Widow Kilbane" leased a 6-acre plot in Carrickslavan townland, Gortbonaugh subdivision, in Carrick-On-Shannon. (I assume the widow was his mother-in-law?)
In 1857, James leased an 11-acre plot in Carrickslavan townland from Gilbert King. No mention of the Widow Kilbane.
In 1870, James was in prison for about a week.
In 1901 and 1911, Anne was a widow, and her unmarried sons James Jr and John lived with her on the same land in Carrickslavan. So James died sometime after 1870 and before 1901, but I can't find a civil or church death record.
In 1913, Anne purchased the land in Carrickslavan.
In the early 1920s, a neighbor bought the "Mattimoe fields," probably after Anne passed away. This was told to me by the person who now owns the land, and whose father-in-law was the one who purchased it in the early 1920s. Local families knew the family as Mattimoe, which they pronounce "Mattimer." And that's how I think it became "Mortimer" when the siblings emigrated to the US.
James & Anne had many children, some of whom have baptism records, but not all. Death records are hard to find, but I did find a couple in Ireland. Kiltoghert parish has no record of anyone from this family of Mattimoes being buried in the Kiltoghert graveyard. We have all three death records for the siblings who emigrated to the US.
Here's who I have for their children:
James (1849-1917 - no baptism record, but date is estimated based on census records and civil death record; he died at the Sligo asylum)
Hubert (b. 1853)
Hubert (b. 1854)
Patrick (1856-1933; emigrated to the US in early 1880s)
Ann/Anna M. (b. 1858)
Jane/Jennie (1859-1963; no baptism record (unless Jane is Anna, above); emigrated to the US in early 1880s)
Bryan (Bernard) - (1860-1933; emigrated to the US in early 1880s)
Peter (b. 1862)
John (b. 1864 according to baptism record; John was in and out of the Sligo asylum over a period of 20-ish years. It's possible he died there, but I haven't found a record.)
Bridget (no baptism record, but a civil death record at age 16 in 1884)
We have no death records for James or Anne. There's a record of Anne being sent to the Sligo asylum back in 1878. It's possible she was also there in her later years and possibly died there. That's a guess based on the family history and what the current owner of the land said she had heard about Anne. I can't find a record of it, though.
