No dates ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Possibly the infant of Jens and Sarine Christensen. Baby Christensen is buried between Jens and Sarine, which I feel strongly indicates that this infant is their child.
The 1900 census lists Sarine as the mother of 4 children with 4 still living. Those children; Hanse, Adle, Carl A. (aka Albert C.), and Anna V.; are all included in the 1900 census.
Assuming the 1900 census is correct, and taking into account that Sarine passed away in August 1901, this child would have been born between 1900 and 1901. Taking into consideration that Sarine was fairly young at the time of her death, there is always the possibility that her passing was precipitated by childbirth complications. This, however, remains to be proven.
