Recently, in researching the Sly family of Calvert County, Maryland in the 18th century, I came across a record which I believe refers to Samuel and William Sly.
From the records of the Prerogative Court, concerning the administration of the estate of the late Thomas Crompton:
Thomas Crompton 27.200 A CA £5399.12.0 £96.10.6 Dec 2 1749 Received from:[long list of names that included William "Slyer" and Samuel "Slyer"].
Even though the person who transcribed the old handwritten court records THOUGHT that the script said "Slyer", I am reasonably confident that it was actually "Slye" with some odd flourish at the end that was mis-interpreted as an "r".I have not found any other evidence that there was a family named "Slyer" in Calvert County before or after 1749, but there was certainly a family named Slye (a/k/a Sly) that had men named both William and Samuel.
Then, a few years later, from the same Prerogative Court records was the following:
James Mackall 33.193 A CA £1270.18.7 £82.7.0 Oct 2 1752 Received from: [long list of names, including "James Duke, Jr., James Duke, Jr. for Gab. Slyer" and more names].
I believe the "Gab." was an abbreviation for "Gabriel" and because this was undobutedly an adult (say, over 21) at the time, this Gabriel "Slyer" (which I suspect was also "Slye" (a/k/a Sly), would have been born before 1731, probably in Calvert County.
If anyone has other information about Gabriel Sly, or other information about instances where a record concerning a William or Samuel "Slyer" might actually have been about a Slye or Sly, please share by posting here or contact me directly at email@example.com.
