I think it's definitely Sands as all the children were baptised and Bridget's maiden name was Sands iirc.
A James Sands was the godparent of one of Bridget's children
However have been on findmypast.co.uk and found a reference to a death of James Sands in Kinsale, Cork in 1837- which could be my Bridget's father/grandfather.
There's another Capt George Sands in a directory of Clonakilty - not sure where that is.
Doesn't look like there's many Sands in Cork so if I find any hopefully they're related.
