David I had already looked at the baptism mentioned
on the parish records film but not posted the info.
as I gathered you were discounting it.

St Barnabas / 1871 / March 5th / number 915
Lewis Henry Killey illegitimate son of Ann Killey
Abode- Hope Street , Douglas. Single woman. Rev. Sutton.

Hope Street is very close by St George's but this
church attracted the well to do & St B poorer folk.
