Can someone give me the names of Roman Catholic cemetaries in Trenton Michigan and or email/fax numbers

The closest cemetery to Trenton is Our Lady of Hope. It is located on Allen Road between Sibley Road and Pennsylvania
I would suggest you also try Mt. Carmel Cemetery located in Wyandotte as many people in downriver lived in other area communities. Third choice is Michigan Memorial as many Catholics are buried out there. I lived is this area for over 30 years.

Our Lady of Hope
18303 Allen Road
Wyandotte, MI 48192

Mt. Carmel Cemetery

At one time St Joseph RC church had a cemetery just outside of Trenton. it's was also called Grohs cemetery. They stopped buring there in abt 1913 for reason that differ with who you talk to. In abt 1965 the cemetery was dug up and all remains transfered to Our Lady of Hope cemetery in Brownstown. I did reseach on the cemetery all all info on it is at the Downriver genealogical Society's library housed at the Taylor Library on Pardee rd in Taylor, MI
