Christopher Black family?

Hello,
My ancestor Christopher Black supposedly died in Hancock County in 1818. I checked findagrave.com, but was wondering if anyone knows of an old cemetery or records that could verify that he was in Indiana and died there. Also looking for his wife, who may have died there as well: Elizabeth Barlow Black.Their son Joshua lived in Indianapolis, but it looks like the whole family moved there from Maryland after or around the time of the War of 1812.
Thanks!
