ohh I have LOADS
on my dads side:
my great grandfather (grandma's dad) coached the first black man in the olympics
and my OTHER great grandfather (Grandpa's dad) was a major contributor and one of the few leaders that led Iraq to rebel from Great Britain after WW1.
we have pictures in my house of him meeting the king of Syria and other countries.
also my grandmother's father was in the british army during WW1 as a messenger, he got to ride a horse from the HQ to the front trenches and back, while his uncle was a Red cross worker (drove a ambulance to the middle of the field/ or trench and picked off and drove back to the Hospital behind the lines.
Cool stuff.
