Milo was the only child of John Edward Clow and his wife Mary Creller.John and Mary were married in St. Armand in 1841, and later moved to Franklin Co, Vt.John died young, in 1853, and after his death Mary returned to Canada where she raised Milo.
Mary depended greatly upon her sister's family for help.Her sister was Hannah Creller, who was married to John Hauver Jr.It is unclear how great a part that John and Hannah played in the raising of young Milo, but they were certainly close.
John and Hannah Hauver were childless, thier only child having died in infancy.I'm not sure exactly when Milo's mother Mary died, but John maintained a strong family relationship with the Hauvers, even into adulthood.
It is Hannah Hauver who is believed to have taken in and raised Florence Sawyer when her parents went to Iowa, so the eventual marriage between Milo and Florence is not surprising.
Hannah Creller Hauver died in 1871, and John Hauver eventually moved in to live with Milo and Florence, until his death.
The CLOW family (aka CLAUW) was Dutch and descended from Johannes and Bathsheba (Bata) Clauw, of Kinderhook, NY.This family came to Canada during the Revolution, with some of the family settling on either side of the border.
All intermarriages in Milo's line came from Dutch family lines, so I think you can rule out any Native ancestry, at least from Milo on back.I don't know anything about the lineages of the wives families from Dana on down.
