The way I understand it, the first Greenfire Farm imports were in the fall of 2010. They were from two different bloodlines in the UK. Some of the hens got Mareks and were lost so rather than keeping two breeding groups all the remaining hens were put in a single flock with one cockerel. That mixed to two lines of Hens breed to a single cockerel was the "A" line.

The pullets from that flock were breed the following spring to the cockerel from the other 2010 imported bloodline. The second flock became Greenthe "B" line.

In the summer of 2011 another bloodline was imported. It was not crossed with the first two flocks. It became Greenfire Farm's "C" Line.

In the Summer of 2012 Greenfire Farm Started to sell Juvenile pairs of Cream Legbars. These consisted of one cockerel and one pullet. One was from the A line and one from the B line. Everyone that got juvenile pairs were mixing the A line and B line in there breeding. The A line and B lines were related to each other anyways though so these two line are really the "2010" line. In the Fall of 2011 Green Fire Farm started to sell day old chicks from the A & B lines. They marked them with different colored legbands so that those intrested in setting up cross pen breeding groups could. In December of 2011 people started to get chicks from all three line. These were legbanded with three different legbars so that again people could set up cross pen breeding groups. In the spring of 2012 some of the chicks were reported to be getting the legbands tangles in the nesting pad that lined the bottom of the shipping boxes. Greenfire farms stopped banding chicks shortly after than so after the spring of 2012 none that got stock from Greenfire had any way of knowing if chicks from Greenfire farm were from the same or different breeding pens. So at that point everythng in became a mix of the A,B, and C lines or the "2012" line. In 2013 Greenfire farm started to beed pullets back to their C line cockerel. It is not clear if there were breeding daughters back to their father, pullet from the A & B line or both. These however were the Greenfire Farm "2013" line. Many people started calling these the "D" liine

In the Summer of 2013 Greenfire Farm imported an additional line of Gream Legbars. This is the only line of Legbars that Greenfire Farm revealed the source of their stock. That line was imported from Jill Rees and is called the Rees Line. It was released early in 2014 as the Rees line it however is not Jill Rees' line anymore but rather Greenfire Farms "2014" line. The 2014 line however was sold separate from the earlier lines so instead of getting a mix of A&B lines like people got in 2011, a mix of A,B,C lines like people got in 2012, or a mix of A,B,C,D lines like people got in 2013 in 2014 people knew that they were getting stock from either the 2014 Rees line or from the mix of A, B, C, D lines.

Hope this helps.
I have read this. studied this, looked at the pictures and I still do not know what line mine are. I know what I was told they are. There is another person on this thread with the same birds as me.
I am going to show you a picture of them when I got them.
We will discuss afterwards so I do not influence you.
BTW they have Minnesota modified combs.. ( frostbite) Anything over a year up here has the same comb.
