Good morning - I would be happy to check into this, once I return home in a week. However, first, there are 2 Maple Grove cemeteries in Leelanau County..since the last name is HarrigEr, I am assuming that the correct cemetery is the one in Empire, since there are many many Harriger families in Empire. Secondly, do you have any idea about which plot or section the headstone is in?
I checked
www.findagrave.com and the only Harriger entered so far, is Evelyn L Harriger Schultz in Maple Grove.
