Well, nice to meet a cousin through the Bartleson line!
Very glad to share info.
My information has Laura's place of death in Burbank, Los Angeles, CA. According to this information, she is buried at Inglewood Cemetery, Incglewood, LA, CA. Is this correct? Regarding westward migration, I have found another descendant who claims that Joseph Kethcart Bartleson, the oldest son of Gabriel, moved west to Kentucky. His son, William Harris Bartleson, migrated to Kansas.
Do you have 13 children listed for Gabriel and Susan?
