I guess I was expecting baptisms of older children (I'm assuming they are not posthumous twins) to be on a Sunday but I may be mistakenly applying today's standards - however the month separation is also interesting.

I have no further records of the name - Ballaugh in 1836 is not the first place I would have looked for an immigrant family with no apparent Manx connection - sometimes retired soldiers operated a public house, as yet I've not looked at the licenses issued in the parishes so can't comment but can't otherwise think what would take him there.
