I have two West and Pack marriages in Cherokee county, but I'm afraid the only Shearer's I have are Mary Polly, who was married to William Preston West and Everett, who was married to Arminda McNabb. Everett was born abt. 1865. Mary was born around 1800.
I may have a couple of your Pack family though, but I don't have too much detail. I have a Mary Pack (b. 22 Dec 1879 d. 26 Apr 1943) who married Issac Marshall West on 22 Dec 1895. They had 10 children. I also have a Melisha Anne Pack (b. 1855 d. 6 Dec 1901) who married John Wesley West.
I'll let you know if I run across any more Shearers.
