Hi MM. Well, Dohn is my middle name and was coincidentally, my paternal grandfather's name. My dad was home in Laos on a furlough to see his new baby boy (me) and just missed my birth when he asked my mom,
"So what'd you name him?"
"Dohn," she said.
"Hey! That was my father's name!"
Truth be told, my mom at the time had no knowledge of that fact as my dad was reluctant to ever talk about his father (he lost him as an adolescent during WWII). Dohn or Don is actually a common nickname in Laos. It usually pertains to a Lao or Laotian that is pale in color (and I am of French descent).
The "121" of "dohn121" is my initiation number in my fraternity, Pi Kappa Phi. Combine the two = dohn121. Just in case anyone was wondering :D
