man William B ROONEY‏‎, son of John ROONEY and Helen Anna HENNIGAN‏.
Born ‎15 Mar 1841 Montreal, Quebec, Canada, died ‎8 Dec 1914 Avon, Stearns, Minnesota, USA‎, 73 years
Tombstone reads born March 15, 1841. He died of carcinoma of the face. He first arrived in the U. S. 1 Nov 1865 from Pig's Eye, Quebec.

An 1896 map of Avon Township, Stearns County shows that William Rooney owned about 96.4 acres in Section 10 of Avon Township (about 3 miles NNW of the city of Avon), and his son J. P. Rooney owned 63.5 acres adjacent to that, including an abode.

The 1900 census shows they had 8 children of which 5 are alive. The 1905 census has an 8-year-old John Rooney living with them, born in New York, his parents born in Canada. He is probably one of the orphan train children; the 1910 census says he is an adopted son.

They also have a William Murphy, age 10, living with them. My guess is that he is their deceased daughter Elizabeth's son, though he's back with his family in 1910.

The 1910 census says they arrived in the U.S. in 1886, but it was perhaps meant to be 1866.

Married ‎1864 Canada
or 1871 per 1900 census
(49 or 50 years married) to:

woman Bridget HARTIGAN‏‎
Born ‎4 sep 1842 Vaudreuil, Vaudreuil-Soulanges, Quebec, Canada, died ‎28 May 1917 Avon, Stearns, Minnesota, USA‎, 74 years
Her 1842 date of birth is on her tombstone, which differs from her death record of 1840. In the 1900 Federal census states that her birth month and year were September 1842. Her Minnesota death record says her year of birth was 1840, which I'm less inclined to think is correct; she should have known better than anyone, while she was alive, what her birth date was.

Children:

1.
woman Elizabeth Ann ROONEY‏
Born ‎29 Jul 1864 Wakefield Twsp, Quebec, Canada, died ‎± 1895 Holdingford, Stearns, Minnesota, USA‎, approximately 31 years
Farrellton, Quebec, Canada is now St. Camillus, Farrellton, Quebec, Canada. She's listed as "Lizzy" in the 1895 Minnesota state census. In the 1900 census, Dan is a widower.
2.
man John Patrick ROONEY‏
Born ‎25 Jul 1871 Avon, Stearns, Minnesota, USA, died ‎10 sep 1942 Stearns, Minnesota, USA‎, 71 years
3.
woman Ellen E ROONEY‏
Born ‎26 Oct 1872 Avon, Stearns, Minnesota, USA, died ‎22 Jun 1902 Sedan, Pope Co, MN‎, 29 years, buried ‎Jun 1902 Padua, Stearns Co, MN
Ellen's grandfather John, given his date of birth, was very probably a brother to Michael Rooney ("Daddy Mick"), making her and her husband Thomas second cousins.

Tim Ahles says: "The Ellen Rooney that married Thomas T Rooney (grandson of Daddy Mick), is from the Rooney branch that we often refer to as the "Avon Rooneys." Ellen's parents are William Rooney and Bridget Hartigan. I do not have any records of Ellen's grandparents, but they might be the John Rooney and Helen Hennigan that you mentioned. We have often suspected a connection between our Rooneys and those from Avon but have not yet proven it."

2017: We have now "proven it" through at least two DNA matches in Ancestry between persons on the Padua Rooney branch and one or two on the Avon Rooney Branch (Andrew Minzghor and perhaps one other).

Cause of Death: Childbirth.
