you might consider being "pro-active". I find that Geni currently has at least 279 people listed with the last name Miale (145 living, of which 37 are actual users). Obviously some of these are already in your tree. So you might want to do a search and working through the list, contact the managers of these profiles.
That might give you some good leads, or at the very least, a list of other Geni editors with whom you can connect. Looks like there are at least three other users who have added lots of Miale profiles. Good luck!
