Hi my name is William Brandstadter son of Marilyn O'brien, grandson of William and Mabel O'brien William Neftelberg before the name change. William O'brien was born in April of 1898. In the 1960's and 70's we lived in Canarsie, brooklyn ny. on east 88th street. Walter's name came up a lot, and I met aunt Frances one time around 1967. I did not know of any other family. If anyone would like more info or would like to add more info feel free to contact me at bil1131@aol.com
