Hi Jack and Pablo
Yes many of thise names you list Jack are connected to the Colhouns that are of interest to me. Starting with John Colhoun of Taughboyne who died 1755 this is his tombstone.
Taughboyne Graveyard
Here lieth the body of Mary Colhoun
Alias Mary Owen who died ye. 9th day of September 1741 aged 70{born 1671}
Also the body of John Colhoun {her husband}who died the 17th day of March 1743 aged 78 {born1673}
Also the body of Mary Colhoun alias
Nesbitt who died the 17th day ***** 1743 aged 38
Here lyeth the body of Mr John Colhoun who departed this life
The 21st April 1755 aged 55 or 85 years {illegible} years
So it appears John was the son of John Colhoun snr and Mary Owens. From John Colhoun jnrs Will it appears that John's son Owens was named after his mother's family.
Next it would seem that John's children (Jack, Andrew, William, Owens and Isabella) were all children of his frist wife Mary nee Nesbitt who died 1743. John;s 2nd wife Elizabeth is not listed on this tombstone.
John names his children in his Will and names his wife Elizabeth and Tristram Cary as executors. Tristram Cary was also the father-in-law of John's son William Colhoun.
Which brings me to the ship Hannah which arrived in Philadelphia Pennylvania on 4 Nov 1807. On which were several Colhoon families including a Tristram Colhoon and a Nesbitt Colhooon. Both unusual names.
A Tristram Colhoun of Taughboyne married a Mary Paterson of Taughboyne at Raphoe on 28 Feb 1778.
A William Colhoun of Taughboyne married a McAusland of Taughboyne at Raphoe on the 26 Dec 1780.
Some of the land at Corncammon that John Colhoun left to his sons Jack and William passed to Jack's son John Cohoun ( surgeon and apothecary) who married Elizabeth Fivey in 1787.

Marriage intended between John Colhown and Elizabeth Fivey. In consideration of £300, John Colhown granted to Hugh Woodney and James Culley half of the townland of Corncamon, Barony of Raphoe, Co Donegal. John Fivey granted to Hugh Woodney and James Culley the part lands of Greenan near Loughbrickland, Co Down, which he was then intitled to under the will of his father Thomas Fivey deceased, and also the part of Greenan lately purchased by him from his daughter to the said Elizabeth Fivey for the residue of a term of 2000 years. Witnessed by Cathe [?] Toubert of Canal St, Newry, widow, and Danl Brown of Newry, attorney.
John Colhoun son of Jack, died 1796 and Mary Gallagher, widow of William Gallagher had claim on the estate. Probably related to this deed. (Deeds courtesy of Matthew Gilbert aka Gilby).

https://www.familysearch.org/ark:/61903/3:1:3Q9M-CSJW-5PWF?i=90&cat=185720Memorial of a mortgage dated May 1787 between John Colhown [Colhoun] of Corncammon, Co Donegal, gent, on the 1st part; William Gallagher of Ruskey, Co Donegal, farmer, on the second. Whereby John Colhoun granted to Gallagher the moiety of Corncammon as theretofore was in the occupation of John Colhoun deceased and his undertenants, and now of the said John Colhoun. The moiety being the north side of the townland of Corncammon, Barony of Raphoe, Co Donegal. William Gallagher to hold with all rights, subject to an annuity of £20/pa, plus a clause of redemption upon payment of a certain sum. Deed and memorial witnessed by Peter McDonagh, not. pub., and Peter McDonagh junior, both of the City of Londonderry.
A descandant of John Fivey Colhoun has had a yDNA test and I am hoping that sometime soon, a descendant of William Colhoun and Elizabeth Roulston of Corncammon will also get a yDNA test done and thereby make or disprove a connection between William's father, Andrew Colhoun of Corncammon (died 1865) and the family of John Colhoun of Taughboyne.
