The Derrick name is of Germanic derivation, and was originally found in various forms in England, the Low Countries, and Germany. Subsequently, some people from those countries emigrated to the USA, to Canada, to Australia, and elsewhere.
Ultimately, these pages will provide as much information as I have (and can conveniently handle) on people with the Derrick surname who lived in the above mentioned countries. At the present, the English information is well developed and is able in a searchable database. The data on people in other countries ranges from very incomplete to fragmentary.
I am currently engaged in enhancing the web pages for the non-English Derricks, but imagine that they will never be as comprehensive as the English pages. Also, I have no information on Derricks who lived in, or are currently living in, areas of Europe apart from the British Isles, and I have no intention of researching, compiling, and publishing any such information (I have to have a life!)
