There are 3 Matisoff families living in Crown Heights Brooklyn, USA.
They all come from Rabbi Matusof, who was a Rabbi from Russia and was (Chief?) Rabbi in Morrocco for a time.
He lives here now on Carroll Street.
There is Ellie and Elka Matusof.
And Shlomo and Pessy Matusof.
I am not sure whom you want.
Plus, there is a son in Brunois in Paris.
All the best,
