Yes, Daniel (my 3rd great grandfather) was in the Pike census in 1850, and also in 1820--He came to Pike County between 1815 and 1820, with his wife Mary Palmore, whom he ostensibly married in Georgia, while he lived there between 1808 and his move to Mississippi.He and Mary (Polly) reared 9 children, born between 1812 and 1835.Louisa was the last one.Mary died sometime around 1850, and Daniel married a Sarah (whose last name is not known to me).It is she who is in the 1850 census.
The spelling 'Burckhalter' may not be a mistake.Daniel signed deeds in Edgefield District, SC in 1807 and 1808 as Daniel Burckhalter.His father was recorded as John Buckhalter, and the family before that was variously listed as Buckhalter, Burckhalter, Burkhalter, Bourghalter, and even Bourghatter.Spelling on census forms was often at the whim of the enumerator, or the person being interviewed.
Daniel is also in the 1860 census for Washington Parish, LA.His son Henry T. moved there early in his life, and died there in 1884.Daniel's son, Flem, b.1830 (my 2nd ggrandfather) reared his family in Pike County, and nearly, if not all, of the Burkhalters around there are descended from Daniel.Marie Luter Upton gives some history of the family in her book, Luter-Davis and Allied Families, and the book of The Silver Creek Simmons Family deals with some of the Burkhalter family pretty extensively.
Most of the Burkhalters (as they spelled it from Daniel's children's time to now) are buried in Pike, and surrounding Counties.My grandmother, Daniel's great-granddaughter Ada Burkhalter Allmand, moved all the way to Lincoln County, and lived in Brookhaven most of her life.
I'm still convinced I can find the definite connection between Daniel and John Buckhalter in SC.
