Hi 
I'm sorry but I can't get a true image 
 
  
 
Can you rescan at 600dpi or more 
 
  
 
, as follows:-
Do a 
Prescan first, and then 
select a small area around your husband's grandfather and do the 
final scan of this area, at high resolution
Then 
repost this part of the image, as large as possible without compression 
 
  
 
Can't promise anything but we will try to get something
