Frank, I do not know nearly enough about my ancestors, but follows is some genealogical info that I have, although I cannot guarantee the accuracy, as it is the product of other's research.I do know that English History books say the name was originally Schir (or brightor shining) Hardt (or heart), and was early spelled "shirard" in England.Sherards were said to be opulent in Liechestershire at the time of the Conquest in 1066 AD.It was said that later Sherards were related to William the Conquerer thru marriage of offspring.The family seat was at Stapleford, and the Earl of Harborough (Benet Lord Sherard) lived at Glatton Hall in the village of Glatton, Huntingdonshire. Both houses are standing, Stapleford being a very fancy hotel, and Glatton being an old folks home.
Upon migration to the colonies, the name was changed around several ways.Many people were illiterate, and were'nt concerned with name spelling due to the job of hacking this great country out of the wilderness.Some of John Sherrar's children went back to correct spelling in later years.One family, the John Holmes Sherard family have always held to the original spelling and still do, now living in Sherard, Mississippi.I descend from Benjamin Sherrod and Clarky Best Sherrod's son Henry Best Sherrod.My ggrandfather became angry with his family over the succession question in 1861, changed our name to Sherard, separated from his family, moved to Cairo, Illinois and joined the Federal Army, and my name remains Sherard.
Another migration was Alexander Sherard, who came from County Antrim, Ireland, settled in Andersville, South Carolina.His descendants are not living in Louisana. Hope this helps, Tom
