Newton Earp

Newton Jasper Earp was the eldest child of Nicholas Porter Earp and Abigail Storm. He was the halfbrother of Old West lawmen Wyatt, Virgil, and Morgan Earp.

Newton was born in Ohio County, Kentucky, to Nicholas Earp and his first wife, Abigail Storm. Newton Earp, and halfbrothers James and Virgil, were close for their entire lives. He married Jennie in 1854. She died before 1887. He ran against his younger halfbrother Wyatt for the office of constable. The Earps may have hoped to keep the job in the family one way or another. Wyatt won by 137 votes to Newtons 108, but their father Nicholas lost the election for justice of the peace in a very close fourway race.
