Hello Apocalypse,
My name is Brent Lang and I believe we are related. My dad would have been your cousin. My great grandfather was Thomas Lang, married to Mary Ann McElroy. And my Grandfather was Norman Lang (who was married to Rebbeca "Ruby" (Welch) Lang) who would of been your dads brother. They had the five following kids who are my uncles and aunts (your cousins): Norman Victor Lang (my dad), Ian Lang, Basil Lang, Dinah Lang and Hazel Lang.
Hope I get a chance to hear from you.
Respectfully,
Brent Lang
