The identification of Henry Harbach (62) seems fairly certain.
The Census records show  that he was born in Dodderhill about 1808-1810.
There are a few Henry Harbach's baptised in this period in Bromsgrove but only one in Dodderhill.  His name was initially recorded as Samuel but the error was corrected in the register to Henry.
Henry's parents are listed as John and Ann Harbach, resident in Wichbold (sic).
Suitable marriage for John Harbach and Ann Houghton found.
Suitable burial and death index entry for Ann found, her husband being John Harbach.
Thus the identification of John and Ann seems reasonable, but some corroborating evidence would be good.
  

There are two possible baptisms in Worcestershire but one of these seems to have died the following year.
Ann Howton - St Andrew Droitwich - 25 Aug 1767 - Benj. Howton and Eliz.

There is another Ann Houghton who married Thomas Smith in 1805.
