Daughter Ernesta Colonomos married Saul ALEVY on 10 Aug 1921 in Manhattan. She writes her parents names are Minsterch (obviously mispelled) and Matilda CAMHI -- not ALEVY.
What source(s) do you have for Mazaltov (Mathilde) being born ALEVY rather than CAMHI?
I've uploaded the marriage record as a document and attached to the relevant facts.
