Hi Angela Webster’s Dictionary (English/American) has under Scud Leather Mfg. v.t. To scrape (a depilated and trimmed hide or skin) in order to remove remaining hairs, lime, etc. Just as a matter of interest, from Google this site shows a proposal for leather to be obtained from fish – it’s a business plan for a company called The Mermaid Leather Co. in Newfoundland, Canada (you don’t have to read all 32 pages!). _http://terra-firma.ca/user/image/5_10_8.pdf_ (http://terra-firma.ca/user/image/5_10_8.pdf) My bet is that a fish scudder was a descaler/gutter of fish in preparation for processing of some kind – smoking, salting, etc You haven’t said in what area your relatives were working or in which censuses you found this information but you could try looking in the _www.historicaldirectories.org_ (http://www.historicaldirectories.org/) website to see what fish businesses/trading firms were around at the time. Good hunting! Ruth
