Jon -

The presence of the "Co-op" in the title suggests an association with a Farm Co-op, and various of those had their "high times" beginning about in the 30s and perhaps a little before. Some continue to function today, although the "Community Spirit" seems to have flagged a bit. Now the remaining ones are mostly just "a place to get feed, fertilizer and seed," and/or sometimes a place to gas up before heading to the nearest "big town" to go shopping.

Depending on the local community, that the songs are mostly hymns doesn't necessarily mean there was a direct church connection. That's just the kind of songs most people knew - and sang when they got together, before radio, phonograph records, and rock 'n roll. Public grade school music textbooks frequently were close to 50% hymns in my area as late as the mid 1950s.

The "two sisters" may have been just local "community leaders." Often a school teacher, librarian, wife of the minister, or (rarely perhaps) the wife of the town banker etc would get "elected" to be the leader of some project, and would feel obligated to take charge.

Small communities could impose an enormous pressure on "somebody" to "organize something," and it was frequently left to the "wimmin folk" to get things organized. The title "Co-op Recreation Service" could mean just that some of the women in the Co-op formed a committee to foster "get-togethers," so the "Recreation Service" part of it could be just the name of - essentially - a women's club (more recently called an "action committe"?) loosely associated with the Co-op.

Virtually anything that happened in some of these small communities got the "Co-op" name tagged on to it, since that was a pretty significant core meeting place in which the whole community participated at least to some degree. The Co-op was usually the meeting place, if not the contributing sponsor for the Boy Scout troop, FHA club, FFA, etc. The women got the feed sacks there for their quilting bees.

Once something of this sort got "organized" and had a successful season or two, the key members often felt an obligation to persist, whether anyone else noticed or not, and often after there was nobody else left in town to notice. Some of these community responsibilities persist until the last key participant dies, sometimes even after that last survivor has moved to another town - or to a care home. (Her daughter writes the new stuff, and puts mama's name on it "out of respect.")

Of course I'm merely speculating based on my observation of a few small towns mostly in Kansas, Oklahoma, and Texas; but I'd expect small town folk are small town folk a lot the same throughout much of the rural and semi-rural US.

Perhaps surprisingly, many small towns do now have some sort of library, and there seems to have been funding to provide (higher speed than I can get) internet connections for just about anyplace with a few books. It is quite possible that the town where your booklets originated may have a "home page" that Google can find, and it might give an email address for the library. Based on my observations here, it's likely that a town librarian is "family" with the older generations of the town and may have extensive knowledge of the people of at least recent generations. The same would likely be true of anyone named as the contact for the town home-page on the web, although not necessarily for the webmeister(?).

Lots of these places have had "town anniversaries" that resulted in publication of commemorative books and/or at least pamphlets that may be accessible through a local person. These usually recite at least some sort of local history, and nearly always include biographical (and often genealogical) information on "significant residents." Given the earlier settlement in Ohio (compared to Kansas and Texas) the town probably had a Centenial whoop-em-up sometime between 1900 and 1950, with a booklet or book with lots of history. The "women's activities" would likely be included.

Again - - I'm only speculating, but looking for a direct contact with the town where the stuff originated may be easily productive of more information than you might expect. Of course it may also be totally unproductive; but where there's a chance ....
