If the orphaned daughters of my third great-grandmother Delaney Townsend Charles ended up leaving their home in Florida to live in South Carolina with someone named Light Townsend as Aunt Fannie's story claimed, it would seem reasonable to discover exactly who such a person was. Orphaned or not, those two girls must have had some family members left with a vested interest in their wellbeing. Even if not, there should be some legal record of who would assume responsibility for the ongoing care of those minors.
The name Light is not one often seen—certainly not now, and in my experience, not a given name I've seen from previous centuries. The rarity of a name can sometimes become a blessing to the stumped researcher, and it was not hard to find information on someone named Light Townsend in Marlboro County, South Carolina, who died there in 1870.
That Light Townsend may well have been the one from the 1850 census, still in Marlboro County, who had in his household a possible wife, four children, and an eighty year old woman named Keziah who likely was his mother. Though the family composition changed slightly by the time of the 1860 census—gone were the eighty year old mother and the possible wife, though a nine year old boy named John R. Townsend was added—judging from the value of Light Townsend's property, he had likely been in that county for quite some time. Unfortunately, his passing precluded his appearance in the subsequent census.
Assuming that was the only Townsend man by the name of Light would be a mistake, however. If we looked in the northern Florida region where Delaney Townsend went to marry Andrew Charles in 1841, we would eventually discover there were at least two other men there who bore the same name, Light Townsend. One was a son of a suspected brother of Delaney, Benjamin, who died intestate; we can see his son Light listed in the 1860 census as one of two ten year old twins in Benjamin's household.
Another Townsend man living in northern Florida—David R. Townsend, whose name appeared as probate judge in the administration of Benjamin Townsend's estate—also happened to have a son named Light, listed in his household in the 1860 census, along with a possible daughter named Kiziah, a name strikingly similar to that of the eighty year old woman living in the South Carolina Townsend household.
If the story we learned yesterday from Aunt Fannie was true, census records would not provide us with any evidence confirming the presence of Delaney's two orphaned daughters in the household of the South Carolina man named Light Townsend. There might, however, be records of proceedings naming a guardian of the orphans. That would be a next step for researching this family story from Aunt Fannie, except for one other detail: I've found those possible orphan girls listed in someone else's household.
