Heber Harris I, Hiram's father, came to America from England around 1790, perhaps with several brothers.  His name was first recorded in the Brooklyn, Connecticut marriage records in 1799. 

In the winter of 1804, Heber Harris, his wife Polly (Phillips) and their three little boys traveled to Otsego County, New York where they stayed until the spring of 1814.  They then made their final move westward, settling on the west bank of Lake Honeoye, New York.  By that time, there were nine children.  Hiram was one of those children.

Hiram Harris had been born in Hartford, Connecticut on November 20, 1800.  In Naples, New York, he married Polly T. Blake of Battleboro, Connecticut, on March 28, 1824.  The Hiram Harris family then moved from Ontario County, New York, to Utica, New York, then to Macomb County, Michigan, eventually arriving in Dryden, Michigan (Lapeer County).

Hiram and Polly Harris had 12 children.  Here are the names the children:
