Note: my main evidence is death notices, which sometimes invited members of associations to attend the funerals. See 'Genealogy research: complete list of fraternal organizations' (at a different site) for a very useful list of abbreviations and names of fraternal organizations.
See also the 91st Pennsylvania's Survivors' association, GAR, and MOLLUS. I have listed fire companies in Fire companies.
