Hi Mark -
The St Helier church register gives the baptism of
Elizabeth Charlotte MURLY on 15 April 1838, daughter of Thomas and Charlotte Ann.
The parents marriage was in St Helier on 10 Sept 1835:
Thomas Gapper MURLY
Charlotte Anne TOOGOODboth residing in St Helier.
and unfortunately, St Helier parish church also records a funeral on 30 April 1838 of
Thomas Gapper MURLY, aged 26 years.
So the poor chap died very young, only 2 and a half years after he married, and two weeks after his daughter's birth. I wonder what his cause of death was?
I hope this helps with your 'brick wall'

Mike
