Hi Lois,
I researched Scott and hope this sheds some light on his life.
In 1880 he and his family were living in Burning Springs, Wirt, West Virginia.
Fish, Margaret, b. OH, 52, keeping house.
William Fish, b. OH, 24, laborer.
Helen Fish, b. OH, 19.
Jerry Fish, b. WV, 14.
Pansy, b. WV, 9.
Aggie Park, dau, b. OH, 29, visiting.
Denny Park, grandson, b. PA, 6.
Scott Park, grandson, b. PA, 3 who coincidentally had measles when the Census was taken.
In 1900 the Parke family was living in Aspen, Pitkin, Colorado.
Andrew Parke, b. WV Nov 1842, marr 27 yrs, engineer stationary.
Agnes, wife, b. OH Oct 1850, had given birth to five children but only four alive in 1900.
Clara, b. CO, July 1885.
Albert, b. CO, Dec 1889.
Scott, b. PA April 1877, single, miner of ores
In 1910 Scott and Mary were living in Skagway.
They could have married in Washington, where Mary was born but rather doubtful. I looked that up in the Washington State Digital Archives and didn't find their marriage info using all three variations of the Park surname. However, all of the marriage info has not been loaded into this database.
They could have been married in Aspen, CO or Skagway. I don't have any sources for Aspen. You can contact the Skagway Clerk's office at 907-269-8899 about marriage records.
It's interesting that on the WWI record, he put down as his nearest relative as his father instead of Mary. Maybe they were divorced or Mary had died by then.
In 1930 Scott and his mother were living in Aspen, Pitkin, CO.
Agnes F. Park, head household, b. OH, 80, widow.
Scott, son, b. PA, 53, miner silver mine.
I'll look again for his and his mother's death info so hopefully you can find obituaries for them.
I did find a Mary L. Parks
Born: abt. 1886
Died: 5 Jan 1949, Vancouver, Lewis, WA per death cert #96.
Source: Washington Death Index 1940-96.
There is an obituary volunteer in Clark Co. at freepages.genealogy.rootsweb.ancestry.com/~obitl/volwa.html .
I searched Ancestry and FamilySearch but didn't find death info for Scott or his mother Agnes. Successful Searching!
