I just today found an obituary for Elizabeth Worster (Myers), dau. of Robert, from the Montrose Iowa paper(d.1924).I surmised (no siblings mentioned in the obit) that she must be a sister to H. Jefferson Worster, whose daughter Amy married (in Montrose) Samuel A. Johnson, a cousin to my grandmother.Amy and Samuel moved away about 1903 to Myrtle Point Oregon, where I recently tramped a cemetery looking for them, -- no luck.
Anyway, your post shows that I was right -- Elizabeth is a sister to HughJefferson, aunt to Amy Worster Johnson.
I am interested in these people and would be happy to share information, although I don't know a lot at this point.
There is another potential connection. My step-great-grandmother who lived in Montrose, Cecelia Melissa Sprague Virts Scranton Rhodenbaugh Johnesse, (long story!)was survived at her death in 1915 by one daughter,Mrs. Mary (Virts?) Worster.I have been unable to figure out who Mary's husband was, but he must be part of these Montrose-Keokuk people.If you happen to know of this family I would be delighted to have the information.
