The story

How Middle Island came to be

From Wikipedia’s history of Middle Island.

Read it all →

The European-American history of Middle Island goes back at least to 1766, when the first Presbyterian church was built. Rev. David Rose, who was also a doctor and a pastor of the South Haven church, covered his immense parish on horseback. He filled his saddle bags with Bibles and medicines to minister to his frontier congregation. In 1766 the parish opened a cemetery just across from the church.
