In the 1910 United States Federal Census, John identified his surname as Elsik. The spelling Elcik appears consistently for the rest of the family. John immigrated in 1891, and Mary followed in 1896.

• John Elsik was born in Austria on 06 November 1866.
• Mary Pelcarsky was born in Slovenia on 06 November 1870.

John Elsik (1866–1941) married Mary Pelcarsky (1875–1936) in 1893.

A cherished family photograph taken around the time of the 1910 census shows John and Mary with all seven of their children:

• John P. Elcik, Jr. (1896–1963)
• Michael Joseph Elcik (1897–1980)
• Mary Anna Elcik (1899–1982)
• Andrew Elcik (1902–1995)
• Annie Elcik (1905–1982)
• Elizabeth Elcik (1905–1988)
• Susan M. Elcik (1910–1977)

Annie and Elizabeth were twins. All of the children except Michael were born in Durham, Androscoggin County, Maine. Michael was born in Lisbon Falls, Androscoggin County, Maine.

Both paternal great-grandparents died in Lewiston, Androscoggin County, Maine. John Elsik died on 24 May 1941, and Mary Pelcarsky died on 23 August 1936.

Notes written by Sylvia Adams referenced burial at Saint Cyril Cemetery. These notes ultimately led to the discovery of their gravestone and revealed a surprising connection between the Elsik and Ilcik families.
