My name is Howard Decker and we're cousins. My mom is Ann Decker, nee Ann Vandenberg, daughter of your Aunt Jeanette, who was my grandma and your dad's sister. We met long ago in a distant decade...I have fond memories of visiting Uncle Harry and Aunt Leona. In addition to the Hefner line that you are researching, I'm very much interested in pursuing the Vandenberg line. My namesake is Howard Vandenberg, your dad's brother in law.
I hope all is well in your family.
My mom and dad are living in Houston, Texas, still, as do I along with my wife of 11 years and son Michael, 7 and daughter Sarah, 4 mos.
