Life: looking for smallest ancestor of a quad-loaf

[Ian Osgood]

Greetings,

I am looking for the smallest ancestor of the following four loaf pattern in Conway's Game of Life:

    **
   *  *
   * *
 ** *   *
*  *   * *
* *   *  *
 *   * **
    * *
   *  *
    **

This arises from random starts quite often for such a large pattern, making me think that it has a smaller ancestor pattern.  Does anyone know what it could be?

(For an example of what I'm looking for, try this pattern to get a quad-boat:

 ***
*  *
*  *
***
)

Thanks in advance.
