Hello. I do volunteer lookups in Coles County. If you wish, please email me direct at keyrse@mcleodusa.net
Some of these boards, not necessarily this one, don't always let me know if there is a reply and I don't want you to think I ignored anyone :)

Okay, I don't find any Mahanes surname buried in Coles County. This is the closest thing I do find:

Dry Grove Cemetery
Maharies, James (son of W&MA) age 18 1841-5/4/1859


If there is other information that you are seeking, please email me and let me know! I do have Cumberland County as well, let me know if that applies & I'll look there.

Good luck,
Kelly
