Mike, I wish I could help you with the Stolzenberger family. I only know what I posted--that one of my paternal great grandmothers was Mary Gunther Roth Stolzenberger who was married to Henry Stolzenberger and that my grandfather Roth (her son) is buried at Green wood cemetery in Brooklyn along with his brother Christian Roth (d. 1899) and two Stolzenbergers (Ambrose Sr. and Ambrose Jr.). It is a large overgrown, unmarked grave. Except for the info on the cemetery computer I wouldn't know who was buried there. I have no idea who these unknown Stolzenbergers are. The Stolzenbergers owned two funeral homes, one on Stanton St in Manhattan and one in Brooklyn. Wish I could help more.
