Dear Family, We will always remember Uncle Mike (Mies) We were blessed to have known him. He was kind and very interested in everything and everyone and always glad he could talk Dutch again when we visited. The three times I came to visit in Canada a visit or even more visits were planned... He was my mum's cousin and ever since I visited with her they had great conversations and kept in touch by phone until the end. He will be missed. We will keep him in our thoughts and prayers. In thought we will be with you all in this time. Although he reached a blessed age, it still will be a great loss.
Nelly Van Berlo 2023-07-27 06:26:54
