It looks like the bloodline that the Old Cotwold Legbar was developed from came from David Applegarth. The only C. Elliot bloodline in the UK was the line that went through Punnett. Elliot didn't keep the blue egg layers he brought back from Patagonia. They were all donated for research and went to Punnett. So... no Elliot bloodlines were in Cotswold. His family, Martin, survived in that that area, but the blue eggs didn't. They went through Punnett who developed the Cream Legbar, then David Applegarth who re-created the degenerated Legbar when it was nearly extinct and breed it back to standard, then Lee-woolf who crossed the Applegarth lines with to create the commercial Cotswold production birds.
