Following the death of her husband Patrick, Catherine McCarty and her sons moved to Indianapolis, Indiana, where she met William Henry Harrison Antrim.
The McCarty family, along with Antrim, moved to Wichita, Kansas in 1870.
After moving again a few years later, Catherine married Antrim on March 1, 1873 at the First Presbyterian Church in Santa Fe, New Mexico; both McCarty and his brother Joseph were witnesses.
Shortly afterward, the family moved from Santa Fe to Silver City, New Mexico. Joseph McCarty took his stepfather's surname and began using the name Joseph Antrim.
Catherine McCarty died of tuberculosis on September 16, 1874.
