Did any People go to Delaware?

I’m searching for my paternal grandfather’s roots. As of 1830, our surname was Chandler.

I know that as of 1830 there is documented proof that his ancestors were here in Sussex County, Delaware. A brother “went West” out to Ohio then migrated to Indiana between 1831 and 1840. I found that brother’s family line.

Per US Census records, in 1820 we have an Augustus Chandler with the appropriate number of children with the proper ages in Sussex County, Delaware. I can find no trace of this Augustus Chandler before or after this time.

Per US Census records, in 1810 there is “Negro Chandler” residing in Sussex County, Delaware. Knowing the prejudices of the times and the system of the US Census that did not always recognize Native peoples, I have theorized that this Negro Chandler was called Augustus ten years later and was my great-great grandfather. I have no other evidence of this man prior to 1810.

Having examined Chandler families in Accomack County and Tidewater Virginia, I have discovered that we do not descend from these peoples. So I must look further west/south in Virginia.

I have come up with a theory that I must now prove or disprove – That our family may have been Tutelo, Saponi or of those areas. That we worked our way north and east. That perhaps a family named Chandler gave us aid to move to our current homeland in Delaware and we carried the name Chandler as our anglecized name. That other family members may have moved to Ohio and Indiana to be close to tribal members.

Now my questions are: Is this theory probable? Did the Tutelo, Saponi and others drop off in Delaware when migrating away from the European invasion? Because the Nanticoke and remnants of other tribes on the Delmarva Peninsula had found isolation and relative security and peace at the headwaters of the Indian River and the Great Swamp – would members of tribes from Virginia perhaps have gone to this area?

Proving this is going to be difficult as my ancestors owned no property, most were uneducated and there are no wills or land records to follow. But I will not stop searching – in the journey there is always knowledge.
