Machynlleth...thats where the little kid April Jones was murdered wasn't it. so sadAh, right. My dad was Welsh too, from near Machynlleth. He got MS at 31 and died at 45. If I look at my family tree, all my relatives from that side of the family married cousins and so forth, in the same valley. I always thought that unhealthy.
No my Dad was from Llanelli, my mum was from Tottenham area.
But you are right. It is not a strong genetic link but there is a genetic association. MS isn't directly inherited, but people who are related to someone with the condition are more likely to develop it, that is true. I am pretty sure it has skipped me...I am too old, so fingers crossed I have not passed the susceptibility onto my two girls.
Fingers crossed for your family t0o Goldie
