It was a mission of Blessed Sacrament church in New Rochelle N.Y..The mission became a parish in 1874, then the present church was built by 1885 and renamed Most Holy Trinity. One of our early pastors, Rev. Isidore Meister, was resp

onsible for the construction of a new stone church building. Parishioners helped collect and save money and the project was completed in 1886. The new building was dedicated on Sunday, August 15, 1886 by Archbishop Corrigan. Since then, succeeding pastors worked to add on to the parish with a school, convent, rectory and gymnasium.
