Geri,
You may have seen this on Ancestry.com, but I thought I'd share:
Imdieke: German: unexplained; apparently a topographic name for
someone who lives im diecke ‘in (or ‘at’) the dike’ (see Dieck).
Dieck: North German: topographic name for someone who lived near a
dike, Middle Low German dik. See also Dieckmann.
Dieckmann: topographic name for someone who lived by a dike, typically
for someone whose job was to control pumps and water levels, a variant
of Dieck, with the addition of man ‘man’.
from the personal name Dieck, a reduced form of the old personal name
Theodicho (see Dick).
Dick: Scottish and English: from a short form of Richard. Although
found in every part of Britain, the form Dick is especially common in
Scotland, and it was from there, in the 17th century, that the surname
was taken to northern Ireland.
German and Jewish (Ashkenazic): nickname from Middle High German
dic(ke) ‘thick’, ‘strong’, ‘stout’, or in the case of the Jewish name
from modern German dick ‘fat’ or Yiddish dik.
German: topographic name for someone who lived by a thicket or patch
of thick undergrowth, from Middle High German dicke, a special use of
dic(ke) ‘thick’.
North German: from a short form of a Germanic personal name Theodicho,
formed with theud ‘people’, ‘race’.
Hope that helps. To me, Imdieck sounds very, very Dutch/Low German. In
fact, I have an Imdieke (last name only) in my Family Tree Maker. I
have record of an Imdieke being married to Anna Hubbert, daughter of
William Hubbert and Katherine Haverkamp. Anna was born abt. 1865 in
Srpingfield, Ohio and died between 1920 and 1939. I wonder if there is
any connection. I'm related to the Hubbert side.
All best,
Andrew
