Here is a photo I took recently of the Vallem plot located at Union Cemetery in Lee county, Illinois.
In the background is the Vallem monument, which I posted in August 2010. In the foreground is the marker for Lena Josephine (Travland), the first wife of Peter John Vallem. To the left of Lena is Peter's marker.
To the left of Peter's marker is that of his second wife, Sarah (Anderson) and to the left of Sarah is the marker for Peter's daughter, Lena Verdelle (Vallem) Dover. The marker says 'Doner' though I am not sure of the correct spelling.
