There are several Christensens in this plot.
L-R: Rosalie (Mother) and Edward (Father)
Behind them is a stone simply named Christensen. This may be the stone replacing the "2 unmarked footstones" mentioned in the Cemetery Directory--and no longer visible.
The tall red stone is Laura Christensen, and behind her, with the military marker, is the stone for Donald.
Near the tree is a small stone, marked Iris C (a baby) and Baby Son.
To the right of the tall red stone is an upright gray stone with surname Christensen--in front of it are the stones for Anna Marie and James C. Christensen.
