Well, this stuff is obviously a bit tricky. Lorna's has about a 60/40 mix on maternal vs paternal, so there's some trouble-shooting to do there. Julie's very nice graphic looks a little suspicious to me at one spot.
So let me go through Julie's. It seems like the way to go is generally right-to-left.
I see about 2/3 of it, on the right, as being all three siblings matching, except for two obvious segments where Julie is the "odd person out". I guess it kind of makes sense that both of those segments are on the same side (meaning her mom's side) since if the crossovers were on different sides, she wouldn't be returning to matching both siblings. Which grandparents these segments come from would all have to determined by matches with cousins.
So far, so good! Then we more to the left, and see that Lynn is now the "odd person out". Presumably, we know he difference is on her dad's side, due (again) to matching vs cousins. All is still good, as far as I can figure!
But the next piece (2nd from the left) is where I wonder if it doesn't add up. Does it really make sense for Lynn to have crossovers on both her dad's and her mom's sides, at the exact same place?
Instead, I would look at "Julie vs Lynn", and expect that Lynn remains "blue" and "orange", all the way back to the beginning. The "vs George" results are still explained by his having a different segment (right where you have it), but I would think it would need to be on his MOM's side, not his dad's.
So, in summary, I would think that Lynn has two segments on her dad's side (blue then pink), and is solid orange on her mom's side, while George is solid pink on his dad's side, with a short green segment of his mom's side interrupting what is otherwise orange.
Really, it also seems like it must be kind of unusual for all three of you to mostly have the same (pink, orange) combination, with some minor exceptions. The chances of having 3 siblings all match at a given point is 1/16, as best I can figure (64 possible combinations, 4 of which have all three matching).
