My mother, her mother, and her aunts periodically worked for the Ryerson/Salvatore family who spent their summers on Otsego Lake, just north of Cooperstown, NY. I remember going with them to open the big house called Swanswick in the Spring, letting the fresh air in and removing the sheets that covered the furniture. This was a relationship that lasted for four generations, as my great-grandmother received an invitation to the wedding of Ellen Ryerson in Chicago in 1917 and my great aunt cared for her children and grandchildren in Cooperstown, Scarsdale, and Washington DC over the years.
As an aside, it was reported that Mr. Ryerson caught the attention of Juliette Gordon, future founder of the Girl Scouts at "an outing in Providence" in 1883, prior to his marriage. See this article.
