Fair point dawnsh. In general I find Deceased Online really useful, but the limited search facilities are sometimes frustrating. Specifically, the lack of ability to search geographically within the UK.
In this particular case, being able to search all Hampstead burials for 1888-89 would be really helpful. I've tried the advanced search with 'include similar names' checked, but to no avail.
In my experience, the staff at the Islington & St Pancras Cemetery office have always been as helpful as possible, but very busy. I swim at the pool nearby, happy to pay a visit this week.
