Teresa,
I always thought Hudson Horsley was a great name. SB Moffatt may have been born 1818 but no guarantee. Len's comments are intriguing If it was him he left a wife and two children aged 1 and 2 behind. There has been some comment from a relative of mine that SB Moffatt may have been in the Indian Army but she hasn't given me any more detail. Do you know if Hudson had any military links?
Cheers,
Ray
