The Sinclairs of Midland, Michigan, descend from John Sinkler, who was perhaps the first Sinclair to arrive on the shores of the New World. This page traces his descendants from 1658 to the family of John Lowrie Sinclair in the middle of the 20th century. For the interesting tale of John Sinkler's capture at the Battle of Worcester, his arrival in the New World as an indentured servant, and his settlement in Exeter, NH, you will want to read about the Sinclairs of Exeter.

     John Sinkler, the progenitor of this family, lived on the banks of Wheelwrights Creek at Exeter, N.H., probably as early as 1658, only twenty years after Exeter was first settled. There is a record to the effect that he (John Sinkler) on the 6th day of Jan. 1659, purchased ten acres of land and he is mentioned in the deed, which is extant, as of Exeter. One authority claims that he was second of the name to set foot in this country. He descended from one of the oldest and most renowned families of Great Britain. He was born about 163?, his parents were Henry and Janet (Sutherland) Sinkler. It is possible that he came from Lybster, Scotland, though this is not definite. He was married twice - history records only the first names of his wives. Mary, his first wife, is believed to have been living in 1669. His second wife was Deborah. On Jan. 7, 1699/1700, he made his last will and testament, the same being admitted to probate Sept. 14, 1700. There is no signature affixed to this document but in place of signature is a circle, known as the Round Robin. His children (all born at Exeter) were:
