Hey back Kim, I know what frustration is with genealogy brick walls.... I'm in four right now. :( Just let me say upfront that I have no relation to this family. The bible was purchased in Webster MO, a municipality inside the city of St. Louis. Webster University is the area it came from.
On to your questions:
Inscription on opening page; "To D. McGowan -Harrison Ohio" Louisville Kentucky is another city.
To clear up from this bible:
The Lorenzo D. McGowan in this case was married to Francis King May 12 1875 as entered. The he married Sadie Kern October 23, 1884 as entered. The entries by family members just gives various names and dates. If this info seems to work I'll scan some pages. I only used the family name with the most family members : Walter, Mabel, & Neal.
