This is a brief history of a few of the ‘formerly accepted bloodlines’ whose names were created by a former breed researcher.  We now are finding upon researching the histories of these goats, viewing original registrations and documents, histories, that much is left out by using some of these bloodline names as bloodlines and stopping with them.  We are totally missing many of the Founding herds and information.  We also are finding that miss-coding is being done on bloodlines, as well as miss-information on some of the bloodlines listed below.  IGSCR is working directly with some of the older breeders, as well as a geneticist to correct and more accurately represent the bloodlines.

Information for the bloodlines that are were accepted years ago is from a current SCI breeder and bloodline researcher.

As a registry, IGSCR has decided not to place bloodlines on Registration Certificates for several reasons.

  1. Still ongoing project, and some bloodline percentages and even bloodlines themselves are being corrected, as more information surfaces
  2. Registration Certificates are an official record of Breeder, Ownership, Identity and Pedigree. This is not really the scope of bloodlines.

Once we complete our decisions on Bloodlines and Founding Herds, we will be creating a new bloodline certificate that more greatly aids in your use of these bloodlines for your benefit in herd management.  It is one tool that can help in your achieving the characteristics of your own herds.

Great care MUST be used when breeding for bloodlines.

  1. Don’t make the mistake of breeding out vital traits of the San Clemente Island that have always been in the goats since the Island.
  2. Beware of Inbreeding Depression.  This is caused by breeding too closely in lines.  Inbreeding for generation after generation leads to loss of vitality and genetic defects.  This is very close breeding.  Inbreeding is not to be confused with Linen Breeding which is breeding of lineages that are not as closely related.  Line breeding can actually enhance breeds/bloodlines, and even save breeds from extinction.

At some point IGSCR hopes to have a Bloodline DNA analysis test created. However, we are far from that yet.


Some of these accepted bloodlines are Founding Herds, and others are 2nd and 3rd generation breeders Blended lineages from different founding herds off the island.

USA Bloodlines and Gene Pools

Shared by a couple of breeders who have done a lot of work on the bloodlines of the San Clemente Island.

Please Note that these bloodline names are shared only because breeders have been using these herd names or bloodline names for years as breeding tools. Neither IGSCR nor IDGR had anything to do with the creation of these names or the history of these names and farms. Many breeders of today insist that these bloodlines be placed on registration certificates. We were complying for awhile, but we no longer are placing these names on Registration Certificates.  Much work must be done on the true bloodlines of this breed, which we are currently working on.  Also working on how to code these bloodlines correctly.

  • AHRENSBERG – (Code on Bloodline Certificate: A)  (Founding Bloodline) Based out of CA but line has since moved to Grace Heritage Ranch in TX. This is our rarest line.  
  • LARRY WARREN (formerly INCORRECTLY NAMED Earth Spirit)– (Code: LW [formerly coded ES by former researchers, but IGSCR has changed this to reflect the true bloodline]) (Founding Bloodline) Larry Warren obtained the goats from Garry Warren, who had them hand-picked for color by Phyllis Larsen and Diane Nelson, who drove them to Garry Warren’s aunt’s house, bypassing the Fund for Animals adoption camp. (History by Laurel )…
  • NELLIE-GAIL – (Code NG) (Blended Bloodline) Some of lineage went to Willow Valley Farms.  Diamond J Farm has a granddaughter of Nellie Gail Granny.  We are unsure yet where or how this herd originated.
  • NEW HAMPSHIRE – (Coded NH) (Blended Bloodline) from Dave Adams, East Hill Farm and SVF (Swiss Village Farm Foundation) and Leslie Edmundson, Little River, in VA
  • PLIMOTH – (Coded P) (Blended Bloodline) named after Plimoth Plantation in MA. This herd was held by the park, Wellsbrook Farm and Nook farm. Origin from registration records: Pine Cone Valley (Island Import), Tepper (2nd generation breeder [see below]), San C [Founding Herd], Alta Mesa [2nd generation breeder]. The main influence in this herd seems to be Pine Cone Valley, with some intermingling of Tepper (Haystack’s). ~IGSCR
  • RIVETTI Ranch (coded R) (Founding Bloodline)
  • TEPPER – (Coded T) (Blended Bloodline) The Tepper herd originated from these farms, according to original registration certificates.  Pine Cone Valley, Daisy Hills, Hartgrove (buck called Andre who is the origin of Sheri’s light tan lineages) these 3 herds are Founding Herds off the Island.
  • CANADIAN Bloodlines and Gene Pools
  • GIL aka Alta Mesa (Blended foundation lines) –  Farm name was Alta Mesa. The BLAKE line from Milton Blake in NC,  was initially based in NC but the last of the Blake’s herd is gone, and part of this herd went to the Gil farm in Canada. We now find that Alta Mesa is a 2nd generation breeder ,blending lines of Blake, O’Ben (O’Ben is founding herd), San C (founding herd) and G’Elf (founding herd).
  • VANCOUVER ISLAND – The Vancouver Island line is is run under the farm name of QLLC  These goats came from Alta Mesa (who are O’Ben, Blake, San C, G’elf. [these breeders were themselves Island Impot breeders and Founding Herds]) Her founding goats were Island Medley’s. Farm name of QLLC.
