LA death records for that time period are not online, yet. So, I can't say anything about the Samuel Lige Spears you mention. I sort of covered Zebadee Spears in previous post. And he is in the information given by Irisgay. Did you read the part about Thomas McBride and when he left LA and went to TX???
Did you look at the same post on WorldConnect that I saw? It was updated in June of 2009 for Susan McBride. The older one is on Jasper Denby and that's not your direct line, anyway. You want to get in touch with the submitter of information on Susan McBride and Jack Spears.
If you do a little hunting I think you can find more. On the Spears forum I entered Lige in the Search This Forum box.
"My g-grandfather was named Lige Spears. He was born 12 Sept 1887 in Texas. His father's name was Sam and his g fathers name was Zebediah or Zeheda. I think that Zeb's father was Lige. They are buried in Slef Grove near Hornbeck, TX."
Or you can enter 216 in the little box that says Jump to # and that one has more on Zeb.
Go back to WorldConnect type in Spears, Lige, first one has him, his wife, father Samuel Loffet Spears etc.
