Hi Kim
Just saw your post from 2006. I visited Inkerman in Mountain Twp. just last week, searching for the Kahala (aka Kahaley) farm located near that village. The family I was researching were also Catholic and they are buried in the only Catholic cemetery nearby, St. Daniel's, located in South Mountain, Mountain Twp. South Mountain is a small village and it only took a few minutes to search the cemetery for the site I was after. This is the url for the old County Atlas of 1874 which shows farm ownership and even has a name search feature:

Hope this is of use to you.
