Frank Milton Peart was born to William B. Peart and Mary Alice Brown in April 1878 in Kansas. Frank would have been a toddler when his father moved the family to Bent County, Colorado, where Frank and his brothers were raised. Frank Milton married Anna Garvey, born October 1887 in Pennsylvania, about 1908.
In 1900 Frank Milton Peart listed his occupation as a cattle driver while in Colorado, a miner coming from Nevada in the Kansas 1915 Census, and a carpenter in 1920 while living in Arizona.
Frank and Anna had two children:
- Lillian A. Peart was born August 10, 1909 in Nevada. She died February 21, 1987 in Los Angeles, California.
- Leo L. Peart was born January 3, 1915 in Kansas. He died September 12, 1975.
Frank Milton appears to have died prior to the 1930 census. Anna is shown living with her two children, Lillian and Leo. Lillian is the only one in the home who is employed. She is working as a bookkeeper for a lumber company.
