But although, in the existing records of the series of Councils and Synods that were held during the ascendancy of Mercia, and often presided over by the Mercian kings in person, the name of Cloveshoe is frequent, as the place of convention; other places, as “Cealchythe” and “Acle,” are also frequent and continuous. And the names of the councillors, who sign the acts as witnesses, have a certain current identity, with only such changes as may be expected by lapse of time, rather than of change of the region where the assemblies had been convened. After the king, usually follows the Archbishop of Canterbury; then the Bishop of Lichfield, followed by the other Mercian Bishops; and then of the other subject kingdoms.

These two places, Cealchythe and Acle, have been as great puzzles to enquirers as Clovesho itself; and they also have been placed in very distant regions; the sounds of their names being apparently thought to be the only consideration. Cealchythe was thought by Archbishop Parker to be in Northumbria; but Alford said Chelsea; Spelman that it was within the kingdom of Mercia.[74] Gibson suggests Culcheth in Lancashire, as although in Northumbria, not far from Mercia. Miss Gurney also says “Perhaps Kilcheth on the southern border of Lancashire.” Dr. W. Thomas gives it to Henley-on-Thames, partly because he considered it “near” Cloveshoe; Wilkins nor Kemble make any venture; others, adopted by Messrs. Haddan and Stubbs, and, as far as the name alone would have settled it, with a very great deal of apparent reason, would have placed it at Chelsea. The ancient forms of the name of Chelsea, of which examples are by no means scarce, seem all directly to lead up to an identity with that of the councils. One of these, of the baptism, A.D. 1448, of John, son of Richard, Duke of York, recorded in Will. Wyrcester’s Anecdota, is, for example, at “Chelchiethe.” But the name of the council seems to resolve itself into “Chalk-hythe,” and there is no chalk at Chelsea. But even this has been got over by taking the first portion of “Chelsey” for “chesil” or gravel; and this favours the ancient forms of Chelsea = Chelchythe, rather more than it does the variations in the name of the council; which on the whole lean towards “chalk” or “Chalkhythe.” Dr. Ingram[75] adopts “Challock, or Chalk, in Kent;” and Mr. Thorpe repeats that suggestion, with the addition of a “?”
