This photo was taken at a celebratory gathering of the descendants of Elizabeth (Norsworthy) Watts in 1928, most probably in Walkerton, Ontario, Canada. Very few of those pictured have been identified. I've listed the existing identifications below.
Can you help by adding another identification (or two or three or ....)?
First row (children) (L-R): #1 Jean Hall (tentative); #2 Emma Hall (tentative)
Second row (seated) (L-R) (including standing child as #1): #5 Avis Norsworthy (tentative); #7 Theophilus John (T.J.) Watts; #8 Elizabeth (Norsworthy) Watts
Third row (standing) (L-R): #1 John Robert Dickson [husband of Henrietta Eliza Watts]; #2 Henrietta Eliza (Watts) Dickson; #4 Juanita (Huntley) Watts [wife of V. Orval Watts]; #5 V. Orval Watts
Fourth row (standing) (L-R): #2 George Hall [husband of Ella Dickson]; #9 Elizabeth Ellen "Ella" (Dickson) Hall
