My late son-in-law's father was Martin Arthur Cogburn. His father was Francis Marion Cogburn married to Mary Isabelle Beasley. I cannot find anything that shows the birth of Martin. Social security Death Index shows his birthday as 2 Oct 1901. The 1910 census shows a Zora or Ziri born in 1901 as a child of Francis & Mary I. Does anyone have any clue whether this is Martin? Trying to do some genealogy for my grandaughter but can't document Martin.
