Hi there. This post was from 10 years ago, so you may have already found your information. Oscar & Pauline are my Great Grandparents. My Grandfather was Louis Selmer. You are missing another child. The youngest was Robert Selmer Born in 1924. Robert was also my Grandfather, my Grandmother Alice married him after Louis passed away at the age of 50.
