This photo was likely taken circa 1941-1942 in East Greenville, Pennsylvania and includes the living children (and/or spouses) of Charles Philipp and Caroline K. (Wolf) Greulich—assuming, of course, that the identifications are correct.
Men (L-R): John Wieder, Lewis Keller, Elmer Greulich, Albert Sterner, Charles Greulich
Women (L-R): Katherine Jane (Greulich) Wieder, Kate Amanda (Weil) Greulich, Anna E. (Greulich) Keller, Lillian Witmer (Snyder) Greulich, Flora (Greulich) Sterner, Carrie A. (Greulich) Letterhouse, Anna M. (Scholl) Greulich
I’m not sure of the identification. I’ve taken the information from another photograph where Bill Wieder, son of John and Katherine (Greulich) Wieder, kindly identified the occupants. Bill was present at the gathering, so I’m trusting his memory. I, unfortunately, am too young to have ever met any of these family members.
