The LaMastus Line Lives!
3rd great-grandfathers (father of Ella LaMastus who married George W. Logan in Cross County, Arkansas). I've now added the line of Edd L. LaMastus, brother of Ella to my file at WorldConnect (click the link up at the top). With what my new found cousin told me, I was able to find Edd LaMastus & family in the 1910, 20 & 30 Census. They were living in Telico Township, St. Francis County, Arkansas in 1910. After Edd's wife Betty died in 1918, they appear in the 1920 census in Heber Springs, Cleburne County, Arkansas and by 1930 have relocated to Lynn County, Texas. I'm not sure why, but in 1930, Edd's daughter Lurla Mae is living with the family of Charles & Etta Davenport in Montague County, TX instead of with her family. Ultimately, Edd and sons Ernest & Val moved on to California where I've found all three in the California Death Index on Rootsweb.
I have to admit, I'd pretty much given up on this family as none of my family around Cross County knew what had become of them, so hopefully now we can reconnect and fill in all these blanks. This is the second line this year that had dead ended for me only to turn up in California. Maybe I should just start my research in California and work backwards from now on!
