Abner Hosmer was a Private in Captain Isaac Davis’ company of Acton Massachusetts Minutemen, and marched on the alarm of 19 April 1775. Abner was killed instantly in the first volley at the North Bridge in Concord.
Abner is memorialized through the Isaac Davis Monument on the Acton Town Common. The remains of Isaac Davis, Abner, and James Hayward (an Acton soldier killed in Lexington later that day) were moved and re-interred beneath the monument.
He was born in West Acton, the son of Deacon Jonathan Hosmer and Martha Conant Hosmer.
