These Behans were also my great grandparents. Another cousin and I are in the process of doing family research. Christopher and Ellen Behan were my paternal grandmother's (Cecilia Behan Kearney) parents. She married William Kearney, and they also lived in Three Rivers before moving to Mishawaka, Indiana. William and Cecilia (my grandparents) had seven children (6 daughters--one died in infancy) and one son (my father Leo Lawrence Kearney). Incidentally, Christopher and Ellen were from County Clare, Ireland. I have more info, but I will await your reply.
