Ashkenzi Jew Link?

Ashkenzi Jew Link? Hi
i was told i has BRCA2 gene 2 years ago and have just undergone a peventitive double mastectomy.
I found out last year that i also have a rare blood disorder called Factor XI (Haemophilia C) i have managed to have 2 children and never had a problem before!
Anyway i have been told is was quite rare but was also told it was linked to the Ashkenzi Jewish population same as BRCA2 gene.
I really dont understand how any of this as we are all red headed irsh decendants!!! or so i thought! haha
So what i am really asking is if anyone else has had the same diagnosis of BRCA2 and then found to have Factor XI deficiancy?
Thanks
Angela
