There is quite a network of Mundows in the Dun Laoghaire area - Glasthule, Kingstown, Monktown in the records, all seem to be related. I am interested in this surname as it seems to be used interchangeably with Muldow, a surname I am definitely interested in. There is a Bernard Muldow who was a sailor who is also referred to as Mundow in records. My Muldows were in the Killiney area.
