CitWW: Bloomsbury Methodist Cemetery 1875 (Multi) Multi-Cache

PLEASE NOTE: This is a level 4.5 difficulty MULTI. It will not be for everyone.

Everything you need to solve it is on the webpage and at the cemetery . Everything is not as simple as it seems. You should expect some hints, a little misdirection, and some head scratching.

If you come to this one and expect a quick find, you will probably be disappointed.
But, msg me and I am more than willing to give "good" hints.

I suppose people do not want to mix puzzlings with multis, or don't like having to think at a multi. Rather they feel everything should be straight forward step-by-step rote follow-the-directions without "hints-that-have-to-be-connected. I am saddened by this. I can remove all of this "field-puzzling" but then I would have to rate it as a D2, not a D4.5.

This is simple two-stage mulit-cache, but not so easy to solve - but then again maybe it is - and another in my "Church in the Wildwood Series" or "CitWW:".

Small country cemeteries are absolutely amazing to me! Visiting them, is like stepping back into another time.

Historically...

Bloomsbury Church and Cemetery was located at Creekbank, on a Fisher farm, at the corner of the Drayton line and what is now County Road 17. It was built in 1882, and served until about 1915, when it was closed. It was dismantled, and taken to Hollen by teams and sleighs, and was rebuilt; and became their Methodist Church, later United Church. Bloomsbury Church was surrounded by a cemetery, which is kept in fine condition by the Alma Horticultural Society. The stones were assembled into a cairn in 1937.
Petherick Bunt (1805-1881) - of Yeovill, Somerset, England - came to Canada in 1839, settling in Vaughan Twp., York County. In 1848 he moved to Wellington Co. and settled near Alma, lot 16 S. conc. 9, Peel Twp. He did carpentry work in first Methodist Church in Bloombury.
