Would you be able to help me...
I have found a picture post card stamped "Runton Sheffield"

The picture is of 2 infantry men... with the following written on the reverse:

"Willie marked with an x / their add. is
Corp. Wm C. Crook
Hdq. Co. 168th Inf.
R.E.F
Pvt Harry E Crook via New York
then the same add. both are some where in France"

do you know who these two might be?
Thanks, Karla
