the quote is from A W Moore "Old Manx families" (also on MNB) - there is a somewhat more detailed tree p199 "Andreas" by Sally McCambridge (available via shop at Manx Museum) + a brief discussion on p 198 but quite a bit more re Ballacorey - however this family does not appear related to the Gilbert Christian you were asking about - also not sure where the Patrick born Ann fits in (? what year)
