Gilligan Funeral Homes is still in business, now with four locations, having bought some other funeral homes, (ex. Siefke).
Gilligan Funeral Homes is online with current funerals at gilliganfuneralhomes.com.
Former Ohio governor John Gilligan and his daughter Sec. Sebelius are a part of that Gilligan family, though not active in funeral part. I believe the active member is (or was) named Harry Gilligan.
