Then I would have a separate label that had the standard stuff: Quilt Title, machine pieced by your name, machine quilted by business name, date finished. So, one label is like the card you give with any gift (except it won't get separated from the gift), and the second is the actual quilt data. Together they give the provenance.

ETA: If you think the second one 'snubs' your siblings, or if you think they might feel that way, it's probably better to skip (or reword) it.
