You need to give a little more information than what you gave, eg name, rank,
and serial number.
I am ASSUMING that he was born in the Kingdom of Hannover between 1830 and
1832, and that his last name is Bloh.
That is like saying he was born in New York (city or state?). You see what I
mean.
The facts you give that he was a shoemaker and lived in Mayenne suggests to
me that he may have lived in the city of Mayen, not far from Koblenz, mind
you, a possibilty.
My next step would be to search the Mayen records for an entry of the
ancestor, since this is the only speck of evidence there is, however a name
would have to be found first. That may be found in his descendants, at least
last name. I also would search for him or descendants comming to the USA,
this again I have to assume that someone came to the US.
Something to work on.
