UK, Civil Engineer Lists, 1818-1930 updated

Ancestry's list of UK civil engineers now claims 194,446 entries. The information contained is engineer’s name, election year, location, and professional position held. As they came out several times a year you can follow changes through the professional career.
Although its a UK list there are a good many people working outside the UK included. I found nine entries for William Patrick Anderson, living in Ottawa, who turns up in multiple other Ancestry Canadian records from his birth in 1852 in Quebec to burial at Beechwood Cemetery in 1927.

This database is in addition to the UK Civil Engineer records and photographs mentioned here.
