David,
Wow, this is a coincidence. I just ran across the name "Dargoon" for the first time on a marriage record while looking up my family -- and a Google search says you and I are talking about the same married couple. The parents of those five sons you mention were Pat McSharry and Catherine Carrigan. I am the g-grandson of Catherine's sister Winifred "Una" Carrigan Guihan, making our grandfathers first cousins and you and I third cousins, I believe.
I was always told by my dad's first cousin, Father Bill McGovern of Worcester, MA, that there was a branch of the family who were originally "McSharry" and were now "Foley." I can identify, as some of my family use "Wynne" and some use "Guihan," which are both also used interchangeably on the old records in Leitrim.
Here's what I have that you may find of interest:
I. Per rootsireland.ie -- civil marriage record 17 Feb.1868 in Drumkeeran Civil Reg. district -- Pat MacSharry, Dargoon, farmer, over 21, bachelor, father Bryan MacSharry, farmer. Catherine Carrigan, townland of Shass, over 21, spinster, father Denis Carrigan [our mutual g-g-grandfather], farmer. Witnesses James Mooney & Catherine MacMorrow. Married in "Innishmagrath" RC church.
II. Per familysearch.org --
(a) John McSharry born 12 Jan 1869 Drumkeeran, Leitrim to Pat McSharry & Catherine Carrigan
(b) Francis b. 12 Feb 1871
(c) Peter b. 12 Jul 1872
(d) Pat b. 13 Jul 1874
(e) Bernard b. 25 Jul 1876
III. Denis Carrigan (b. circa 1792, died 2 Jan 1880 in Shass) appears on both the 1834 Tithe Applotment and the 1856 Griffith's Valuation land records in the townland of Shass with his single brother John. Their landlord was Hugh Lyons Montgomery, who was sort of infamous in that area from what I understand. Denis' wife was Mary (our mutual g-g-grandmother - b. c. 1802 - died 12 Nov 1877 in Shass). I don't know her last name, but it could have been McMorrow or McMurray; she also may have come from up near Manorhamilton originally according to Father Bill McG. The Carrigan family were the masons in 1735 for the roofless chapel of Kilbride in the parish of Innismagrath; legend (and written parish history) says that it was always roofless so that the parish could evade the Anti-Catholic Penal Laws. When it came time to pay the Carrigans for their work, there was no money, so they gained the exclusive right to be buried inside the chapel. You can see Denis and Mary's headstone right inside the chapel doorway -- it was erected by their single son John Carrigan (died 15 Apr 1905 age 75 - your g-grandmother's brother - a retired signalman who worked on the northern railway in England). The three branches of the Carrigan family in Innismagrath are the "Mansheen," "Patsy Donal," and "Thady" Carrigans, which I think could be the names of the brothers who built the chapel. Our branch are the "Thady" Carrigans. The children of Denis and Mary that I know of (not sure of dates of birth or birth order) were Francis (who got the Carrigan farm in Shass in Inishmagrath), John (who I mentioned above), Michael (of Blacklion), Anne (m. Patrick McManus of Alteen), your Catherine McSharry, and my g-grandmother Winifred/Una, who married Philip Guihan of the townland of Cavan in the parish of Inishmagrath.
IV. I don't think Dargoon / Dargoone is the name of the actual townland. There was a Catherine McSharry of "Dergvone" on the 1901 Irish census who died in 1902 as Catherine "Foley," widow of Patrick. Not sure if this is right person or townland. And another complication -- because they were on the border, you may have to look at both the parish of Innismagrath / Inishmagrath in Leitrim (Drumkeeran area) and Co. Cavan (I think the parish of Killinagh). After seeing your note, I looked up "McSharry" and "Foley" in the Griffith's Valuation records on askaboutireland.ie and found four -- in Inishmagrath, there was a Denis who had land in the townland of Geaglom and Francis and Darby who had land in the townland of Greaghnaglogh; there was a Pat Foley in the townland of Kiltyfeenaghty Glebe.
I'll do some more hunting in my stuff for you to see if I can find anything else. Hope you find this of interest!
