Thank you so much for helping me by providing the information I have been searching for on my great grandmother. I can go visit her grave now that I know where she is.
It helps to have a little more information on Gertie to maybe locate my grandfather's real father. Gertie apparently had my grandfather Bert before she married Reints Joustra who adopted my grandfather. Gertie apparently divorced him and then married Jacob Lambert.
Boy, lives get pretty complicated to try to figure them out.
