Carrie or Carolyn Kern

Am looking for my paternal grandmother's family. born in 1894 married to Samuel Souter in 1911 or 1912. Possibly her mother's name was Anna Kern. I think that she might be from either Brooklyn or NYC. After she abandoned my dad when he was 3 wks. old at NYC Foundling Hospital she basically disappeared in a puff of smoke. I believe Samuel divorced her a few years later. According to my dad's birth cert. her name was listed at Carrie SOuter, maiden name Kern. They lived at 493 2nd Avenue, NYC. ANy help would be greatly appreciated.
