Abstract
Marshall [1, Figure 9] gave an example of a polyomino, 8 copies of which tile a square. He asked if this was a sporadic example of a rectifiable polyomino, or if it could be generalized to give an infinite family. We give one way to generalize his tiling to give an infinite family of rectifiable polyominoes; we do not claim that it is the only way to generalize it.
