You have to google Drøhse and not Drohse. Remember that Danish has eight vowels, a, e, i, o, u, æ, ø, and å.
Here is one site http://www.brasendroehse.dk/droeslgt/gustav%20droehse,%20192...
and another http://www.brasendroehse.dk/webtrees/family.php?famid=F12&am...
Let me know how it works out. To find Anne Drøhse I looked at over 400 pages of documents.
