When you said family member, I don't think copyright is a problem. I Agree with WildGoose that the trace result isn't bad. One way that might allow you to fine tune the results, but might take some effort is to get some tracing paper, a dark pen or marker, and trace it manually by hand. A lightbox helps. Scan that and try the auto trace again. When you are tracing by hand with the marker, only trace the outlines of the shapes, skipping any shading or hashing. This might in the end leave you with something easier to correct.
