You seem to have a lot of information on the Deys in the New York/ New Jersey area.I'm taking a long short, but we're looking for a James Day who was born prior to 1775 based on the 1820 census records in Mississippi.He died in 1827 shortly after he and his family moved to southern Indiana, in Washington County.In the 1880 census, two of his surviving children said he was born in New York.Another child said James was from England.
In the Day family DNA project, it came back that we were a direct match to some Days from the New Jersey area.This has led us to search more closely in that area for the origin of our James Day.We believe he was married and had several children.When and why he moved to Mississippi, we don't know, but he shows up there in the 1813-1815 time frame.He serves in the Miss. Volunteer Regirment during the War of 1812.In 1815, he remarries to a "Polly" Brent and they have several more children.In the 1820 census, there seem to be some older children probably from the first marriage living with them in Pike County, Miss.
I know there isn't much to go on, but is there any James Day or Dey living in New Jersey/New York in the early 1800s who moved to Miss in your records????
