Lines and Families

When the founders of the Riverhill kennel were scrutinizing the pedigrees of all English champions and CC-winners, they came up with the system of Lines and Families.
The male Line is the top-level line in a full pedigree (of the sire). Or to put it in other words: it is the sire of the sire etc of any dog. The bottom line in a full pedigree (the dam of the dam etc) is called the Family-line or Family in short.

Lines

Line Line named after Foundation sire Important dog
CHE Chestnut Rainbow Nesting Topper Many behind Chestnut Rainbow
BB Butcher Boy Butcher Boy Many behind Wallace
LJA Lerwick Jarl Thor Some e.g. Eng. Ch. Woodvold and Alford Clansman (Can)
IH Inverness Hoy Inverness Hoy Some e.g. Eng. Ch. Walesby Select
DL Dornoch Laddie Bobby Lad Some e.g. Eltham Park Advance
LWW Lassodie Willie Winkie (but no member of LWW)
Willie Winkie (real member)
Rover Rare
TPR Tresta Prince Prince Haakon Extinct, however Ch Larkbeare Rusk created a large branch. Especially in the Netherlands.

Nowadays of the 7 Lines, only 2 exist worldwide: Chestnut Rainbow and Butcher Boy. This doesn't mean, however, the other foundation dogs don't have any descendants nowadays. It only means, they don't have any pure male-line descendants.
