McShane's in Taney County Missouri

Hello McShanes.... My name is Victoria Boydd and would like to know if there is anyone out there that may hold the answer to my McShanes...After my grandfather Marcus McShane passed away I was given the following information regarding his family. I was told that my McShanes are from County Tyrone..but I have no proof. My Great great grandfather Francis McShane is named in the 1860 census of Taney County, Missouri as being born in Ireland. He came to America as a small boy 12 yrs) with his parents. Perhaps someone reading this can identify with the following McShanes and share information with me...I would very much like to know more information regarding my Great great grandmother Catherine King...I have absolutely nothing on her. It was told to me by my grandfather that his grandfather Francis was killed sometime after 1861(the year my grandfather was born) by Bushwackers....he and some of the children were murdered...my greatgrandfather was saved by his sister Molly. My Great Grandmother Katherine was supposed of have died about the same time with an infant child from small pox or something like that.My great grandfathers sister (Mollie or Mary McShane)married into the Fulbright family.If any of this sounds familiar I'd love to hear from you. The following was copied from an the entry in the family bible: Francis McShane b. 7/15/1815 Ireland m. Catherine King b. 4/9/1827 on 12/11/1843. Born to them: John McShane 9/18/1845; Francis Marian 2/28/1848; Isaac Henry 10/19/1849; James Madison 10/19/1851; Mary Elin 1/18/1854; Andrew C. 1/18/1856; George Patrick 6/7/1858; and my ggrandfather Alexander C. 7/15/1861. There is also a couple of notations on this page as well....Mr. Andy J. McShane Detroit, Michigan, Mrs. Mollie Harris, Conway, Mo. also shows this address: 9611 Delmar Ave. not sure if it goes with Michigan or Missouri address.
I also have the birth records of the children of my great grandparents Alexander & Emma (Muse) McShane: Everette Cornelius 11/3/1884 Berryville, Arkansas; Oliver Henry 4/12/1886 Berryville, Arkansas; Flora Ellen 10/13/1889 Berryville, Arkansas; Ova Georgia 8/29/1893 Temple Texas; Jeff Davis 2/191895 Temple Texas; my grandfather Marcus James 6/29/1899 Hutto Texas.
