You do not say where this story is 'told'.
No Capt. Huber / Hoover / Huver / Hover is listed in F. B. Heitman's /Register of Officers of the Continental Army/, which does list some officers of State Troops and militia.
There is no Capt. by such a name listed in Clements and Wright's /The Maryland Militia in the Revolutionary War/ (Family Line Publications, 1987). The book lists no Weimer/Wimer, and lacks any rosters from Cecil County, but does list commissioned officers.
You can search the rosters available in the published MD Archives in Vol. 18, here:http://www.msa.md.gov/megafile/msa/speccol/sc2900/sc2908/htm...
It is possible that such a person was a militia Captain early in the war.
All free white able-bodied males aged roughly 16-60 (varies by time and place) were required to be available for militia duty for defense within the County. Many rosters survive that were written when men turned out for regular drill and nose-counting, but few militia units had any active-duty service. So often there is not much to say about County Militia other than that they existed.
I'd suggest going back to your source and asking for a first name for the Captain.
