Here are some of the sharper pictures from a pile of loose pictures of Isabel, Henry, and family.
This one shows Joan and her grandparents Isabel and Henry. The original is very faded and also very "silvered out" or tarnished, which makes it extra-challenging, but with some contrast enhancement we can see it a bit more clearly:
Here are Isabel and Henry from their 50th wedding anniversary. This is a detail from what is probably the clearest photo I have of the two of them. In the collection I also have an invitation to their wedding, circa 1901, if I recall correctly, and the guest book which includes the guests from the 50th anniversary party.
Here is another shot of the somewhat mysterious Uncle Will!
