This surname, most often spelled Crockett, has two possible origins, but as our line is Scottish, it's most likely derived from the Gaelic Macriocaird, meaning "son of Richard". Its use dates back to the late 1200s, and gained popularity in the 1600s. Our own line, however - well, you'll see. We know absolutely nothing about them, folks. Nothing.
John Crocket
We do not know when or where John was born, aside from it being somewhere in Scotland, sometime in the late 1700s. He married Emilia Kennison, and the two had at least two children. No date of death has been found for either of them.
John and Emilia's children:
Mary Ann Crocket, b. 1810

Mary Crocket 1810 - Unknown
We don't know much more about Mary than we do about her parents, though we can at least pin down an actual date and place of birth. Born (likely in January) in 1810 in Angus, Scotland, Mary is the first known child of John and Emilia. In 1830, she married Alexander Strachan, and the two went on to have at least four children.
