If you call the front row the one with the three girls and one small boy, Dad is in the second row fifth from the right with the sweater on. Further to the right and at the end of the photo is his brother, Eugene or Gene. Though Gene was two years younger than dad, he started school the same year, which was common during those days. The girl next to Gene is Isabel Dalrymple, one of many Dalrymple's in this school. Mona Dalrymple is the middle girl in the front row, Isabel's sister.
