I am doing genelology work for my 90 year old friend. She married a Max Dinkelman. She says he changed the spelling of the last name from Dinkelmann(2 N's she says; I don't know where)to the current spelling. She doesn't know about his family. Do you have anything in your ancestory that could match this? He died in Illinois. If you could help us out with any info it would be greatly appreciated!
