WOW! What a small world. We lived in Pelham Bay also, just off the Hutch. I went to PS71, we moved to Rockland Cty in 1966 after I finished 4th grade.
I went to Out Lady of the Assumption school just down Middletown road from PS 71. Small world. We moved to the Island. Suffolk county in 64.
My parents went to PS 71.
I went to St Helena’s HS just off the Hutch by the Whitestone bridge for grades 9-10. Went to Commack HS 11-12.
