I have recently transcribed the parish register of Bulley and you should note there is a gap in the register from 1784 to 1806. I tried to fill this gap using the BTs, these also had gaps but covered the years 1787-1799 and 1804, 1805. The means that the period 1800-1803 in not covered by either the BTs or parish register which may explain why Samuels baptism is missing.

The Churcham parish registers have

Charles Cressel son of John/Mary bapt 13 May 1810

Charles Cressell son of John/Mary bapt 28 Dec 1806

Anne Crossell dau of John/Mary bapt 20 Jan 1800

Mary Crossell dau of John/Mary of Bulley bapt 16 Jul 1797 (also in Bulley register)

John Crossell son of John/Mary bapt 5 Jan 1794

As Bulley was a Chaplery of Churcham it is common but not certain for baptisms at Bulley to be included in the Churcham register.
