Overcome one, Encounter another

Well, now that I have tracked down relatives I'm anxious to find out more. Only to run into another brick wall (my head hurts). I am looking for anything for Minnie Myrick (Myrack). Born in Texas December 19, 1879. She married Milas Lemay in Bowie County, Texas, June 1, 1894. She died in November, 1953. This would be my Great Grandmother on my mom's dad's side. I believe Minnie had a sister named Susie Ann or Susie Anna. I have tracked down census records for 1910, 1920 and 1930 for Minnie and a marriage record to Milas. However, I can't find anything prior to 1910. Nothing that tells me what her parents names would be or if she has other siblings. The same goes for Milas Lemay. They lived most of their lives in Arkansas.
