If your grandfather was Patrick "Perry" McDonell and he was the son of Catherine Harriet Quigley, then you would be related to me. I am a great-grandson of Perry's older brother Duncan ("Dakota Dunc")who returned to Glengarry County to take over lot 28/4th Lochiel for his uncle.
Our ancestor Owen was a rather prominent citizen in Lochiel Township during the nineteenth century. The following is the entry on him from Royce MacGillivray's excellent "Dictionary of Glengarry Biography" p. 658:
QUIGLEY, OWEN (died 8 or 9 Aug. 1878, aged 61 or 66, or c. 59), entrepreneur. Owen Quigley, Esq.) Born in Ontario of Irish descent. Parents: John Angus Quigley and Mary C. McCormick (d. 23 Jan. 1874, aged 87. Owen Quigley lived at Quigley's Corners (now known as Lochiel), Lochiel Township, GC. At this location, he opened a general store and a hotel, and he or his family operated a grist mill, sawmill and potashery.He is described in Lovell's "Canada Directory" of 1857 as a resident of Quigley's Corners in GC, and as postmaster, township clerk and treasurer, superintendent of schools, and general dealer. He was clerk of Lochiel Township from 1851 to 1871. Quigley's Corners was named after either him or his family. The Quigley's hotel, used for township council meetings for many years, was demolished in 1932. Roman Catholic.He was married in St. Finnan's Church, Alexandria, 10 June 1848, to Catherine McDonell or McDonald. (children: at least three) She predeceased her husband, her burial taking place on 30 Jan. 1862.

His family is kind of hard to track down and verify. I believe that he was married twice. He had a son Charles born in 1840 when he was married to an Elizabeth Robinson. I have no details on her at all.
He married Catherine McDonell in 1848 and had the following children:
1. John Ranald (10 March 1849- 23 Feb 1871) died out West.
2. Helen Mary (16 August 1850 - after 1901) m. John B. Warren of Vankleek Hill.
3. Donald (20 March 1852 - ?) Also called Daniel
4. Catherine Harriet (1855 - 17 November 1927) our ancestor. Married John Duncan McDonell 28/4 Lochiel. I think that he died about 1920.
5. Charles (28 January 1856 - ?)Either this Charles or the first Charles inherited the eastern half of 26/5 Lochiel in 1878 from his father.
I'd be very curious to hear the story you have heard about Owen. I understand that he might not have been a particularly easy person to get along with. Any other details you have would be of great interest and of course, any questions you may have, feel free to contact me.
