The photographs in the gallery on this page show the children of Dr. Joseph Sailer, 1867-1928, and Mary Lowber Strawbridge Sailer, 1875-1963. Click on a thumbnail image to see it at a larger size.
Based on the ages of the children, I believe the picture of the children in a line was taken in about 1919. From left, the Sailer children in that image are: Anne West, Albin Penington, Elizabeth Twells, Priscilla Sparks, John, Joseph Jr., Mary, and Alice. Anne West died in 1922. The others survived to adulthood.
