Weeks became engaged to one of the Haymaker girls who lived in Charlestown, Indiana, but she died before the wedding took place. Meanwhile, Weeks' family had moved to Tacoma, Washington, but he returned to Indiana and asked his late fiancée's sister Maggie for her hand in marriage. She accepted and they were married in 1891, at the bride's home in Charlestown. He and his wife would later have nine children, of whom only five survived to adulthood. They moved to Tacoma for a period, but eventually moved to Oakland, California along with Weeks' family.
