Yes, that is the place I am considering - the glen, or perhaps the river next to it is called Ballalinnag. I have been wandering around the house trying to pronounce all these names in what I imagine to be a labourer's Manx, and have come up with quite a few different phonetic spellings myself. I have forgotten my tortured logic for now, but I am looking to link this Crowe family to the family of John and Jane Crowe in Ramsey, who in 1851 appear to have 2 sons, aged 11 and 8, both called John Crowe - very odd.
Thanks for checking Ballalionney/ Balliona/ Ballalonna for me!
