Coon Descendants, by Frances Davis McTeer, 1979, (pg. 217-218): "Son of Reddick and Elizabeth (Alltizer) Cartwright." ... "In 1852 when twenty years of age Elias Jackson Cartwright moved to seek his fortune in the west; he crossed the plains with an ox team when cholera was prevalent and helped bury many who had died with that disease. On arriving in California he first engaged in mining on Nelson's Creek, Butte County., where he was reasonably successful. But after a year he returned to his home in the east and to farming. In 1863 he returned to California with his family and took up a ranch of 160 acres near Dayton, Butte Co, but he sold this property in about a year and again returned east, being gone about eighteen months. It was on their next trip back from Illinois that their fifth child William David was born in 1867 in Wyoming. At this time they settled in the same location in Butte Co., where they purchased 320 acres; Mr. Cartwright bought and sold land in this vicinity until at one time he owned one thousand acres. `In a single year he harvested 18,000 bushels of wheat, which was an average of thirty bushels to the acres.'
