As I live in Newtongrange I'm curious about Mrs Cosgrove. Could somebody post what Lloyd published about her?

There are no Cosgroves in Newtongrange now (the mine closed in the early 1980s and any miner who could left to work somewhere else) but there are a lot in West Lothian, and I'd bet some of them are related.

Where are Lloyd's research notes for that book? The Scottish Mining Museum is in Newtongrange - they'll have the book, but they really ought to have copies of everything Lloyd recorded about the place.
