Hi I too have a Christopher listed on my tree but no dates. He would have been a son to Frederick Arnoldi a native of Germany. Christopher did have 4 daughters and 4 sons. Frederick Arnoldi was born 1745 and died 1812. this info comes from my great great uncle Ed who lived in Wallaceburg in the vicenity of Chatham Kent County Ontario. I hope this helps you. I know this is not much but is from a relative I have met many years ago.
