Hi Noeline,
Always better to have information twice than not at all.

If you contact the tree owners you may learn something new - for example the owner of the Kinney tree may be able to tell you more on the daughter of Edward and Gerturde who married into the Kinney line and has 3 children. They obviously also have the name of the son if you explore the tree.
Edward and Gertrude did not marry until 1935 in Michigan so both of the children are still living people, so cannot do anymore on here. Perhaps the release of the 1940 census in April will also help in your search.
Hopefully someone will see you messages on here and get in touch.
