I has been a while, but I can sort of fill in your blanks and will have to jog my memory a bit. There is a lot of family connections which kept thing going.
Here is a brief Wikepeidia link. [en.wikipedia.org
First off JRS was the son of the of the founder of Christian Tabernacle in Washington, Iowa. John had I think 3 sisters ( I'm a a blank right now so I may have to do some correcting).) Mary married Bill Arnold missionary pastor in Hawaii before it was a state.
Eva married Fred Bickhart. They were missionaries in South Africa. They had 2 children Dan and jeannie. Dan married a CA friend of mine- they divorced. Jeannie married steve Arnold and Iowa boy ( related to bill arnold.)
JRS married Martha Michealson in 1939. they had 2 daughters. The Micheal son was a musical family with a number of Christian recordings. ( Perfect marriage partner fora preacher's wife) Her brother was an organist for I believe Billy Grahm crusade. Martha's sister Mary married Harold Williams - they were missionaries in Brazil. They had 3 children. Diane married a Robbins son , John married ? and Paul married an Iowa girl- they lived in Brazil - Paul dumped the former Iowa wife for another woman. ( see a pattern?)
I think the 2 daughters of jrs and Martha were Mary and Martha
Mariyn was his secretary. I met her the first time when I visited my sister in south gate and the Valley ( a number of Iowa girls were moved in CA in the '60's) I was in high school but my teen age opinion first impression of this beautiful lady was that she was like a junior high girl chasing a boy whom she had a crush. I did not look up to her...
JRS performed the ceremony in Ananhien for marlyn son married Tammy Pf iefer daughter of John and Brenda Pf eifer they divorced.( Mispellings make it harder show up on google)
I did not know GH first wife but I understand the dear lady was pregnant with there child when it was announced the god wanted and M him to marry.
Please gives some slack to the dear people who married into the family and left marriages by divorce. I personally have a number of family ties by marriage only.
Hope this helps answer your question.
