He was the son of John Cottrell (1774-1857) and Mary Polly Stillman (1779-1852) and a brother of Solomon Gates Cottrell (1803-1887). That would make Roswell F. Cottrell a great-uncle to Carl C. Cottrell.

Roswell F. Cottrell was raised as a Seventh Day Baptist and kept the seventh-day Sabbath all his life. In 1851 he accepted the hope of the second coming of Christ and joined the group that eventually developed into the Seventh-day Adventist Church.
