I found more report cards for Gertrude and John Whitby.  These are printed on card stock from Phoenixville High School.  Gertrude’s are dated 1913-1915 and for some reason stop at her sophomore year.  Her daughter Grace (my mother) has stated that Gertrude did not finish high school.  The cards for John are not dated but do reflect his sophomore, junior and senior years.  John did go on to further his education at Pennsylvania State College (now Penn State Univ.) and in the US Army.
