QC, this group is far too small for a statistically significant number of diabetics (or Jews!) Also, you don't seem to be distinguishing between Type I and Type II, which are genetically quite different (although both seem to have genetic tendencies that are passed in families, Type II much more so).
Anyway, although I am not a diabetic (yet, anyway), there is Type II diabetes in my family. My dad has it, and several of his older relatives (a great aunt of his and I forget who else) did too.
All Jewish.
