I have been looking for any additional sources of information regarding this Family line and how they are connected to the Doremus family. To date I have more questions than answers and do not have enough confirmed to voice my opinions. In what you have written regarding Sylvester, you show place of birth listed as England and then in Scotland. In the context of the time, why would a black man list those? Was he a freedman that retained the family Surname? Was there an intermarriage in the early 1800's? Did Sylvester travel westward with other Doremus family members after the War for opportunities and settlement [Indiana/Michigan] or did he come from the Doremus' of Louisiana?

Thus far I have only found one reference regarding a slave transfer in a will, making "Freedman" a possibility, and supported by several public family condemnations of slave holdings in early 1700's. The family dynamic would lead more to "Indentured Servitude" of which family members had been bonded and released.

I have also been looking for information regarding Maude "Tille" Odell Doremus, actress.
"Tillie" Maude Odell Doremus (1870 -1937): The stage career of Beaufort's best-known actress spanned almost forty years (half of that time was with the Shuberts in New York). Doremus appeared for 400 nights in The Prisoner of Zenda, her first real success. She went on to appear in The Student Prince, Show Boat and Tobacco Road (in the role of Sister Bessie Rice). Maude Odell Doremus was found dead in her dressing room just before the curtain was to go up on a performance of Tobacco Road. The cause of death was a heart attack. According to former Beaufort resident Brent Breedin, Ms. Doremus owned what was then known as the Edward Barnwell House (now the E. G. Dowling residence, 1405 Bay Street in Beaufort), which was bought soon after her death by sheriff James Edwin McTeer.
