This is an alternative photo of the lady who may be Elizabeth Warnes née Olson, half sister of my grandmother, Hannah Warren. The first photo is at https://gwulo.com/atom/12909 A second photo, taken a few moments later, is in the Olson collection and identified by the Olsons as Elizabeth. Our photo has been labelled "Dorothy Dransfield" by my Warren cousin, who tried to put names to the people and places in her mother's album after her mother's death, but whose identifications aren't always correct. Dorothy Dransfield was a friend of the Warren family in the 1920s and 1930s, but I think this photo represents an earlier era - perhaps around 1915 or 1916. Elizabeth died in 1917.
I don't think this photo will help to pin down the location, but you never know. Perhaps the gate still exists!
