Hello Fran,
On the family search birth entry for Pat Creaton - 19 November 1873 it gives the birth place as French Park. Roscommon. Ireland.
http://www.rootschat.com/links/0cqq/ A family tree entry for a Thomas Creighton born 1886 French Park. Roscommon shows he arrived in 1905/06 according to the Census data and married a Julia Shanahan 15 November 1918 in Chicago Cook. Illinois. The birth date is a few years off the 1882 you give but could he be a possibility.
Thomas Creighton died in February 1964. Julia in Dec 1968. Daughter Geraldine 1918 - 2003 (married to a William Clair 1917-1995) The son Thomas born 1926 in Chicago, Cook Co., Illinois Died April 1973 in Chicago, Cook Co.,
http://www.rootschat.com/links/0cqr/ In 1910 Thomas was in the household of another Thomas Creighton aged 50 years and born 1860 Ireland and is described as a cousin. Would that fit with your Thomas ?
1920 shows this Thomas with wife Julia and a child.
http://www.rootschat.com/links/0cqs/ and 1930 shows him with a wife and 2 children
http://www.rootschat.com/links/0cqt/ The WW1 Draft for this Thomas gives a birth date of 4 th November 1885. Thomas has the occupation of Policemen.
The WW2 Draft also gives a birth date of 4 November 1885 Roscommon. Ireland. The person that will always know him is his son of the same name.
