Thank you Charles for your speedy reply and that clears up something that was a mystery to me. I was always told my g grandfather Martin (Mark) Tuxson was a first generation american so when the name John Tuxson showed up in NB I was confused.
Interesting though that he, Mark, is listed in the 1890 NYC directory with a Charles Tuxson, a first name my family has never heard of. I also might add that it was always family oral tradition that Tuxson was a misspelling, my 79 year old Aunt says she thought the real name was closer to Tuchjon. Oh well, the search continues. I will be up in NYC in Dec and hope to have time to check the census for these names. Thanks again you have been a real help! Linda Tuxson
