To keep our Pootman/Putman relatives up to date: I have located a Victor Puettmann who was born about 1700 in Duelmen, Germany, which is just above the Lippe River and just above the Ruhrpott. The word "putt" with an umlaut over the "u" or the English equavilent "puett" means a well. The Rutgerus Putmanus family of the Lippe River area used in its coat of arms a puteimer, which really might be a well-bucket. There are three [water] buckets on the coat of arms of this family.
The De Plater family originally came from Hemmerde, Germany, which is just east of Unna and between the Ruhr and Lippe Rivers. The Y-DNA of the Dutch-American Pootman/Putman is identical to the De Plater family's Y-DNA, and the names Pootman, Potham, and Poetman and Brule the ancient name of the Broele-De Plater family are common to the area between Unna, Geseke, [and Duelmen] Germany.
I don't know if we are related to Victor Puettmman or not, but it does appear that Johannes Pootman's father was a Victor Pootman [Puettmann?] likely of Aalburg, North Brabant, Netherlands. Victor Pootman was born about 1620 while Johannes or Jan was born in 1644. There is a possibility that the Pootman and Puettman families are connected.
There also was a Victor Putman who lived just south of Ghent, Belgium, during the early 1800's.
In Belgium the name Putman likely means wellman or pitman as does the German surname Puettmann. In Belgium Pootman likely means portman of gateman while along the Ruhr River the name Pootman is more likely connected with Pothmann and Poetman, which seem to mean Poolman or Puddleman, which is also connected or corrupted from Puetmman [Wellman]. A pool today in German is "pfutze" while a well is a "putt".
I have seem a connection between the surnames Pootman and Portman in the Ruhr Valley although it appears closer to the Belgium border.
