What type of diabetes does you family members have ?

As you may know there are two types of diabetes ; type 1 and type 2.

From what I gather genetics are involved in both but type 2 diabetes is more
dependant on genetics. From what I gather as well at least one of the two types
of diabetes, type 2, is multi factoral (several factors combine to cause the disease).

You might find the following info helpful (From WikiPedia) :

"The cause of diabetes depends on the type. Type 2 diabetes is due primarily to lifestyle factors and genetics.
Type 1 diabetes is also partly inherited and then triggered by certain infections, with some evidence pointing at Coxsackie B4 virus."
