Looks like we have the same family. I have the family as follows:
1.IRVIN L.4 SMINK(JOSEPH P.3, WASHINGTON B.2, JACOB1) was born October 02, 1886 in Shamokin, Northumberland County,Pennsylvania, and died October 20, 1974.He married NORA H. DUNKELBERGER Bet. October 1914 - March 1915.She was born Abt. 1894 in Pennsylvania.
Child of IRVIN SMINK and NORA DUNKELBERGER is: i. JOSEPH5 SMINK, b. Bet. April 1920 - March 1921, Pennsylvania.
Do you have anything to add besides the data in your post? Can you provide parents for Harriet Nora or Nora Harriet Dunkelburger?
I have been researching the Sminks for several years now.My common ancestor with this family is Jacob Smink, my family dead end!
