I came across these journals that were digitized by Google and have a lot of
interesting information about the iron casting trade in the 1900's.
It has lists of members that were issued union cards,deaths of member,and
even some pattern making details.They list the members by city ie (Tamaqua,
Troy,Detroit,etc) so you may find your family name in the extensive lists.There
are pictures even expense reports,and use of prison labor in the work force.
They were fighting for a 9 hour day and $2.75/day pay and wanted the seal on
more stoves and ranges their members made,kinda like the Union label Ads that
used to be on TV.http://books.google.com/books?id=sKKfAA ... pa&f=false
Forgot to add that this also covers our Canadian neighbors too, Ottawa, Vancouver,Preston,etc.
