Closed Hungarian Church

[Fülöp]

Hello,
My great grandparents (Vincent and Mary Domos) lived in Delray on Keller Street (the house no longer exists) and I am trying to find out more about them (I don't know anything about the Hungarian side of my family). I know that Holy Cross is a couple of blocks away from their house but I also know that there is another Hungarian Church right down the street from Holy Cross. Does anyone know the name and/or history of this church? I know both my great grandparents were born in Hungary (don't know where) and I am not sure if they were Roman Catholic or not.

Thank you,

Phil
