Gilmore - County, Tyrone

[celticmolly]

I am looking for information on my family I know they are the Gilmores from Knockaraven, Omagh, County Tyrone. My great-great-great grandfather was James Gilmore and he came from Tyrone in 1847, the link is his grave stone (he was buried in Colorado) and bio; http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSvcid=238417&GRid=77057943&
His father was James Gilmore Sr. who was married to Matilda(h) Smith - I cannot find anymore information on either side.
James Gilmore Jr., was married to Elizabeth McCaskie, I cannot find any information on her family either; she supposedly came from Ireland also.

Any help is greatly appreciated. Thank you so much.
