Yes - as I said at reply #15, William Ganderton Scott (whose father was another William) seems to be a red herring. He did exist, but is not the person who married Rosina (his wife was Charlotte).
Rosina’s husband was a different William Scott, son of George. This William born c1832 (according to his marriage details) was the same sort of age as William Ganderton Scott - hence, presumably, the confusion. However, his birthplace is presently unknown - he may not have originated in Birmingham.
