Hemochromatosis is known to run in my father's family - My paternal grandfather had the condition, and so does one of my uncles. I am a known carrier of one of the associated genes as well.
Spina Bifida runs on my mother's side - My mother, her sister, and my younger brother all have SB Occulta, which is the mild variant of Spina Bifida/SB. My maternal grandmother also had a son that died within 24 hours of his birth. The cause of his death is unknown, but I suspect it may have been due to a more severe variant of SB.
I understand there is still a lot of information unknown about these conditions, but I was wondering if anyone knows of what types of records I could look for, to see if any ancestors had these conditions.
