The family of Kellogg originated in Northern Essex. It occurs also as Kelhog, Kylhogge, etc, meaning a hog bother. The earliest known in the direct line was Nicholas Kelhog, of Debden, Essex, born about 1480 and found there starting in 1515. I have collected others in that area from the Court of Common Pleas, manorial, lay subsidy, and other records. All of these are from an area within about 10 miles from Saffron Walden. I don't know how they are related, but those names Rich alias Kellogg (and variants) must be related.
Shalford and Bocking, Essex- Walter Kelhogg, of Shaldeford (Shalford), Essex, husbandman, found in Common Pleas, 1418, born about 1350-1390.
- John Kylhogge, of Bokkyng (Bocking near Braintree), Essex, husbandman, found in CP 1446, born about 1390-1420. Possibly the son of Walter; Bocking is just a few miles from Shalford.
Linton and Carleton cum Willingham, Cambs- Thomas Ryche alias Kellog, senior, of Lynton (Linton), Cambs, husbandman, found CP 1469-1499, born about 1430-40. In the 1490s called Kellogg, the Riche part has been dropped. Linton is a few miles north of Saffron Walden, Essex.
- Thomas Kellog, junior, of Lynton, Cams, husbandman, found in CP 1496-99, born about 1460-70, son of Thomas senior.
- Thomas Kylhogge, of Carleton, Cambs, husbandman, found in CP 1488-90, born about 1430-1460, possibly related to Thomas senior and Thomas junior. Carleton is a few miles northeast of Linton.
- Simon Kellok or Kylhogg alias Riche, of Wyllyngham (Willingham), Cambs, husbandman, found CP 1531-1535, born about 1470-1510. Willingham is now in the same parish as Carlton.

- John Ryche alias Kellogg in the lay subsidy rolls in Little Sampford (less than a mile from Great Sampford) in 1525 and in feet of fines (land conveyance) in 1540-43, born about 1480-1500. Possibly the son of William.
