Welcome from Ontario, Canada. I would lay it out fairly straight and measure the fabric for borders. I wouldn't stretch it in case some of the seams let go or the fabrics fray. I would do one large border all around the top and then re-square the quilt top. You can cut quite a bit off of a large border without it being too noticeable that you've cut more off one side than the other. You might try an asymmetrical border setting( more on one side than the other) and embroider the family history on the larger side border?
