He was never adopted to begin with. It's just a theory others keep bringing up largely due to Lincoln's hair color if it's not about his sisters. The other reason is him being different, but that's a shallow thought because the girls are different from each other in a number of ways. Any excuse to keep that adoption theory alive...
