Dear Teresa,
Looks like your father served in WWII:
"United States World War II Army Enlistment Records, 1938-1946," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:K85X-HNM : accessed 17 March 2016), Ronald F Kelsey, enlisted 31 May 1946, Cp Lee, Virginia, United States; citing "Electronic Army Serial Number Merged File, ca. 1938-1946," database, The National Archives: Access to Archival Databases (AAD)(http://aad.archives.gov : National Archives and Records Administration, 2002); NARA NAID 126323, National Archives at College Park, Maryland.
And maybe his father was born in New York. Take a look:
"New York State Census, 1892," database with images, FamilySearch(https://familysearch.org/ark:/61903/1:1:MQS2-TTX : accessed 17 March 2016), Mirchel F R Kelsey, 1892; citing Walton, E.D. 01, county offices, New York; FHL microfilm 832,853.
Hope this helps! Welcome to WikiTree. -NGP
