Hope your brave uncles returned safely...
The Margraten graves are 'adopted' by Dutch people in the area (they contribute for the maintenance).
There's a long long waiting list to adopt a grave, people haven't forgotten what your uncles and their buddies did.
Also to this day we read about 'new' cases where people in US are contacted and later on meet with people here, that somehow had contact in WW2.
Beautiful to read about stories of people 'finding' a soldier in the cemetory that they knew in WW2, and then telling the children/grandchildren fe.
