For practical reasons I am focusing my Coldingham one-place study on the pre-1820 period. Later records such as census returns and civil registration records have been heavily transcribed and indexed already, and indexes and digital images are readily available at websites such as ScotlandsPeople.gov.uk, findmypast and Ancestry UK. I see no benefit in my reproducing the excellent work they have already done. I can make more of a contribution by focusing on the earlier period.
Church of Scotland parish registers before 1855 for Coldingham are also indexed already, so I will not be reproducing that here. The indexes are freely available now on ScotlandsPeople with links to pay-per-view images of the original records.
For early maps of the Coldingham area please visit the National Library of Scotland’s online map collection. Their digitised maps include earlier maps of the area, as well as later Ordnance Survey ones, including large-scale.
Also worth visiting is ScotlandsPlaces.gov.uk which includes many digitised tax records, especially from the 18th century, and other resources such as the Ordinance Survey Name Books from the 1850s which include detailed information about the history of specific places in Coldingham parish as remembered at that time. For early place names it is also worth checking the National Library of Scotland’s place name index for Blaeu’s atlas of 1654. It includes some place names not recorded on later maps.
The Coldingham pages in GENUKI (the UK and Ireland genealogy information service) contain information about numerous local genealogy resources. In a similar vein the Borders Family History Society have a very useful Coldingham page, which also includes details of the many local genealogy publications they sell.
The Scottish Borders Archive and Local History Centre in Hawick holds numerous local records, many not digitised. They include school records, parochial board minutes and accounts (later poor relief), local crime records etc. They are well worth checking out.
Finally, the St Abbs Community Website has a lot of information about the history of St Abbs village (originally called Coldingham Shore). As well as articles about different kinds of fishing, the website includes a photographic archive of over 100 old postcards showing images from the village and surrounding area.
