Hi! William McDevitt and Catherine Coyle are my 3rd great grandparents. They married in Doneyloop, County Donegal, Ireland (just across the border from Tyrone) on 3 May 1859.
Their 5th child: Margaret (Maggie) McDevitt married John Harrison, 28 Aug 1888, at St. Pius V church in Chicago are my 2nd great grandparents.
You have it a bit incorrect ... Mary 1874-1921 (Died Chicago - Married Thomas Gallagher) ... this Mary was born 6 Mar 1861 in Kilclean, and the rest is fine. She is the eldest child.
The 2nd child is William, born 8 May 1863 in Kilclean.
The 3rd child is Eleanor, born 19 Mar 1864 in Kilclean --- but she is NOT the one to marry Edward Francis Gannon .... that was a younger sister Ellen.
The 4th is Edward, born 4 May 1865 in Kilclean.
The 5th is Margaret (from above) born 1 Aug 1866 in Kilclean.
The 6th is Ellen, born 27 Oct 1867 in Kilclean, married Edward Francis Gannon on 19 Jun 1889 at St. Pius V church in Chicago, Cook County, Illinois
The 7th is Elizabeth, born 13 Jan 1869 in Kilclean.
The 8th is Patrick, born 25 May 1871 in Kilclean and died 6 Apr 1937 in Castlederg Union Hospital, County Tyrone ... and appears not to have married or had kids.
The 9th is Catherine (Kate), born 6 Jul 1874 in Kilclean, died in 1955 probably in Kansas City, married Frank J. Cunningham 28 May 1896 in Denver, Colorado. They had one kid in Denver, two in Illinois, and then 6 in Kansas City, Wyandotte Co., Kansas
The 10th is James, born 23 Sep 1877 and died 26 Jun 1899 in Kilclean, no marriage or kids.
The 11th is William John, born 21 Jan 1881 in Kilclean, married Margaret Ann (Annie) CATTERSON in 1906 in Ireland.
So four of the sisters did immigrant, 3 to Chicago, one to Kansas. I think the son Edward also immigrated, but not proven.
