Based on Joan's data Corrine is the only Pupkin surname listed in the 1926-1949 birth indexes which includes parents.Matter of fact, no Pupkins in any of the other indexes either.(Marriage, Divorces, Deaths)
Corrine Pupkin and A. Dudley Shapere had Abraham Dudley Shapere in Cameron county in 1928-05-27.
This entry is the only entry for the Shapere surname in the indexes.I have a feeling the variant of the name is Shapiro.
There is a birth in Cameron county in 1945 by Abraham Shapiro NMN and Saralee Peterkofsky had Martin Henry Shapiro.Also, a Abraham Shapiro died in Dallas county 1997-12-25.
I looked for different spelling of both surnames but to no avail.
