This photo from the Mearns Family Album is identified as Minnie Johns. I don’t recall seeing this name among the many relations that Iggy has found, but it’s entirely possible I am just not remembering well. The photo can be dated to the 1890s because of the scalloped edges of the card. You can also see the puffed sleeves of her dress and the high collar that were both popular in the 1890s. The photographer was W. C. Bell at 6 West Market Street, York, PA.
UPDATE: Iggy found that Minnie Johns, daughter of Rev. John Henry Johns of the Presbyterian Church of Zion, married Robert Grove on February 5, 1890. In August 1890, Robert passed away after an illness and Minnie was suffering from a bout of typhoid. Minnie’s father and husband are buried next to each other in the Zion cemetery that Iggy visited earlier this year, and the graves are not far from William L. Mearns. Rutledge Gifford was an usher at Minnie & Robert’s wedding. Happily, Minnie survived the typhoid fever and went on to remarry W. R. Stephens on February 5, 1893. What an odd coincidence that she selected the same date for her second wedding as her first! The same minister preceded over both wedding services as well.
