Walter & Iola Clark-Mt Holly, NJ 1950's

I'm trying to locate my cousins: Mary, Julia, Betty and Irene Clark.They are the children of Walter and Iola.Their Grandmother Pearl (Harrington) Hanyon is my Aunt.I remember visiting them in the mid-1950's with Aunt Pearl.I sent Christmas cards from my mother and the family, but the box that had their addresses in was lost when my mother Florence Harrington died.If any of this info sounds familar please contact me at:
