If you have a website with Nemmers, Ley, and related families please let me know so I can post your site here! PLEASE NOTE: The following was received from George Adams (a Nemmers descendant & brother of Jim Adams). I hope the Nemmers researchers find this helpful:

I was looking at a road map of Belgium & Luxembourg (Michelin #909) at B&N today. It lists Tintange (Luxembourg province, Belgium), Tuntange (in G.D. of Luxembourg), and Fort (apparently in Lige province, near the Dutch & German borders).

I couldn't find Tuntange or Fort on the map. Tintange is about halfway between Bastogne and Arlon, just off hwy N4, and almost (<2 km) on the Luxembourg border.

Interestingly, the words Tintange and Tuntange are pronounced identically in some French accents (e.g., a Parisian accent), although they are pronounced differently in "standard" French. A non-French speaker would have a hard time distinguishing the difference between the "un" and "in" nasal sounds, however. I know I did when I was first learning French. (George Adams, 29 Sep 2001)

More on the Nemmers family history from Steve Nemmers (07 May 2001). (Nemmers History #6)

A history of the Freymanns, starting with Caesar's conquest of Gaul (part of which would become Luxembourg), tracing Freymanns from about 1700 in the towns of Mamer and Olm, Charles Freymann & Nicolaus Nemmers' journey with all the families (Nicolaus' wife was Charles' sister) across the Atlantic and the US to St. Donatus, the migration of Luxembourgers from St Donatus to LeMars, and ending with brief sketches of Nicholas' children, the 3rd generation in the US. It is 54 pages long.

The Nemmers family figures only tangentially in this history, but it might possibly be of interest to Nemmers researchers.

The second (and last) printing will be sent to the printer by the end of January 2000. If you should want a copy, John G. Freymann will be happy to send you one for the cost of printing and mailing, which is $12.50.
