I am always looking for new information!! Your great-grandparents are my g-g-grandparents. Their son, Bennie, was my grandfather's father.
I have a good bit of information about Gustav and Augusta, except where they are buried. I am still looking for information about Gustav's parents.
Do you happen to have a picture of their gravesite or of their children? I am always looking for new pictures to fill in the gaps in my database. I don't have too many pictures from that long ago, but I do have pictures of Bennie and Oscar (gravesite) if you are interested in those.
The best I can tell, Gustav and Augusta immigrated to the US from Sweden in 1892. They arrived in Philadephia and seemed to move directly to Manistee, MI. I'm not sure why, they may have had other family in the area. They had 10 children, among them, my g-grandfather, Bennie Gustav.
