Text of article by Beatrix F. Cresswell in Devon and Cornwall Notes and Queries, Vol.X, January 1918 - October 1919, pp.19-20[1]pp.19-20:

"Blagdon Memorials, St. Michael's Church, Honiton (replying to an earlier article in Vol. IX., p. 253, par. 206). — Although many memorials perished in the fire which destroyed the old church of Honiton in 1911, the Blagdon monuments are still there, The floor slab of John Blagdon, 1694, in the north chancel aisle, somewhat injured, but still legible. The larger monument, described by Davidson (James Davidson's MS. notes on East Devon Churches, bequeathed by J. Brooking-Rowe to the Exeter City Library) as "a marble tablet between two fluted Corinthian pilasters," was destroyed, but has been replaced by a marble slab now on the south wall, upon which the old inscription is repeated, with three coats of arms. Davidson mentions three shields on the old memorial, but there are several discrepancies between the arms as he describes them, and those on the present monument ; nor are the arms on the latter correct. The arms given by Davidson are as follows : —

1. Azure 3 trefoils slipped argent, on a chief indented or, 2 annulets gules (Blagdon) impaling : Gules on a chevron between three trefoils slipped arg. as many pellets [Searle.]

2. Blagdon impaling : Per fess azure and argent a cross-crosslet fitchee and an eagle's head erased in chief the same in base counter changed ; on a bend over all three cinquefoils argent — (Gill.)

3. Quarterly 1 and 4 Blagdon. 2 and 3 argent on a chevron azure 3 bezants bet. as many crosses-crosslet fitchee gules — [Crossing] ; on an inescutcheon of pretence — (Gill.)

Davidson has amended his MS. so much that readers are left in doubt as to whether he gave the arms from the monument or corrected them from some authority. I am inclined to the latter view, because in 1906 I noted the first of these three shields as it appeared on the monument :

Azure 3 trefoils slipped argent, on a chief indented gules 2 annulets or ; impaling gules on a chevron argent between 3 trefoils slipped of the second, 3 pellets.

Burke gives the arms of Blagdon as : Azure 3 trefoils slipped argent, on a chief indented or 2 annulets gules ; and Davidson corrected his notes accordingly.

The shields on the new monument display : —

1. Per fesse gules and azure in chief 2 annulets, in base 3 crosses argent, for Blagdon.

2. Blagdon, impaling Crossing.

3. Blagdon impaling argent on a bend sable 3 mullets of the field.

It will be observed that the arms of Blagdon are now incorrectly represented as " per fess " instead of with a "chief," and the trefoils are turned into crosses."
