I made a comment in the thread Dennis W. links to in support of creating profiles for those who died shortly after birth or in infancy. But I'm not sure whether the arguments in favor of such profiles should carry over to stillbirths or not. For what it's worth, in the U.S. Census records for 1900 and 1910, married women were asked to report how many children they were mother of, and how many of those children were still living. I have read that the census enumerators were instructed that stillbirths should not be included in those counts. (I can't recall where I saw that.) If you choose to create a profile, be aware that there may be a potential inconsistency in the available data and records that ought to be explained in mother's bio.
