Thought I’d mention a few web sites I’ve found excellent for padding out the detail of my Scottish ancestors’ lives.
National Library of Scotland’s digital gallery – access point to historical maps of Scotland, Post Office directories, gazetteers of towns and parishes, plus lots of other fascinating stuff.
Statistical Accounts of Scotland – a very good read to get a feel for where your Scottish ancestors lived. The Old Statistical Reports were published in 1791-1799 and the New Statistical Reports in 1834-1845.
Brilliant site if you have Scottish coal mining ancestors. Lists of mines, copies of housing and other reports, and an index of coal mining deaths and accidents
Access to Scottish historical tax rolls from 1645 to 1831.
