I don't know the family, but the website known as Anybirthday.com has Richard SESSA born Apr 16, 1951, living in zip code 98103 = 3 cities in WA.
Using that d.o.b., I went to
http://www.people-finders.ws/and they said his current or recent address is in Seattle, WA. I couldn't find him in the free phone directory, so maybe he has an unlisted phone number. Peoplefinders charges $9.95 for the address, which is not guaranteed to be current. I have no personal experience with any website that charges a fee.
