Holy Trinity's church bell was cast in Amsterdam in 1753.

   Our church had its beginnings, as in many localities where early settlers were German, with the union of the Lutheran and Reformed churches. We began according to the oldest church record  book, "in the year of our Redeemer Jesus Christ 1777."
   Together we built a union school house near the site of the old Reformed Cemetery. The following account was written in our record: "Both the above named congregations have in the above named year united together to build a good schoolhouse to have their children instructed in the word and grace of God! Also, on certain days, to hold public worship in it, as well as reading of sermons on Sunday by the school teacher, or other religious books by a person who is a member of one of the congregations; also at certain times to preach in it by certain ministers of the honorable Reform Classes and Ministerium who pay a visit and also attend to the sacrament until either congregation is in good condition to build a comfortable church."
   The following is a time line of historical events in our church:
