From the same photo album as the others:

On the back it identifies them as (top row, l to r) Keith, 11 yrs; Scott, 8 soon; Billy, 9 yrs 9 mos; (front row, l to r) Lowell, 18 mos + getting over the flu; Lyle, 4 yrs 9 mos. It was taken in 1961 and Lyle's had just about enough of this nonsense. This has got to be one of my favorite family photos of all time and, again, I have no idea which side of the family these boys belong to.
