Surname is Armstrong. He passed away last year. I never knew him. Desperately looking for half-siblings from confirmed previous marriages, it's word of mouth, but that's all I have. They would be much older than me, probably by 20 years or more.
Worked on the Armstrong tree for months.
His name was Albert Randolph Armstrong, (went by the name Randolph)
B: Sept 25 1938, Coffee county AL. My mother is living, but she was divorced from him. Her surname was Hilburn.
Any leads, advice or help would be much appreciated. Thank you.
(Have already contacted my first cousins from his brother's marriage. They don't know anything.)
