We find these as children of his son Herbert Lawrence Herman (who is listed as born in 1925)
Sarah Yablon = Sarah (Herman) Yablon born 1902
Не показывать = <private> (Herman) Graf
Clara Yablon = Clara (Herman) Yablon born 1900
Julius Herman = Julius Herman born 1899

Plus one more that is Private - do not know if that is Meyer or who it is.
But folks born 1899 thru 1902 cannot possibly be children of someone born in 1925
