Those articles are very helpful. However, I believe the original inquirer has most of the information needed to answer his/her query. His/her other posting seeks information on Caterlins from Arkansas that settled in California. That's where Thomas O. Jr.(?) was born and died. His mother was Dovie Parker who wed his father 22 Sep 1923 in Independence County, AR. Thomas O. Sr.'s parents are a mystery that can possibly be solved by purchasing a copy of his, or brother Henry's, original social security card application? Their mother could have been the daughter of Martha J. Clark or Martha E. Mathis? Robert F. Lassiter married (1) Martha J. Clark 24 Nov 1867. Later, 18 May 1873, he married Martha E. Mathis. He evidently loved Martha(s)?(lol) Anyway, Martha Mathis brought children who blended with those of Martha Clark. Confused? Me too!!! See "Garner/Vaulner Family Tree" owned by franeperl58 at
