Matthew Cuthbert was the first of the kindred spirits. He rarely talked but Anne knew what he was thinking most of the time and he knew her just as well. He was extremely kind to Anne and gave her love. The best part about him is that he never noticed that Anne grew up. To him, Anne stayed young. After he died, Anne still felt loyal to him.
Diana Barry was the second one. She was Anne's best friend and swore an oath to be eternal friends with her. She is not kindred enough to know what Anne was thinking, but she understood Anne as a friend and they told secrets to each other. They have never quarreled in the whole series.
Gilbert Blythe was the fifth one. After Anne apologized, he became a close friend and eventually married her. At first Anne didn't think he was the right one for her, but realized it when he was dying. He was very patient and waited a long time before they could marry.
Paul Irving was the seventh one. Anne was instantly charmed by his imagination and knew he was a kindred spirit. He had imaginary rock people when he was young, but began to outgrow them when he was thirteen.
Jim Boyd was the eight one. As Anne and he saw to the first look they know that they are kindred spirits.
