Re: Harrison's Landing on Tittabawassee River
I don't know about this business but generally a Landing on a River meant that someone operated a ferry and it landed at that spot.
There is more info about Andrew Harrison at www.findagrave.com.
If you'd like to find more info, you can contact the Gladwin County Genealogical Society of Michigan, www.gcgsmichigan.org/
and/or the Gladwin County Historical Society, www.gladwinhistory.org/.
By the way, tomorrow Genforum becomes a read-only web site. You can post new queries on www.ancestry.com
