Hello, I dont know if this is any help, but My father is James G. Grewer and my grandfather is David M. Grewer. The majority of our family lives in San Jose Ca. I know that David has a brother that lives in Southern Ca. I think he is in Palos Verdes but I am not sure. I have also found it very difficult to get information on a Grewer family tree. To the best of my knowledge, our family is of Scottish acncestory. It is great to see people taking an intrest. If any information is discovered, please post it for everyone to read. Take Care,
David Grewer
