At Graceland Cemetery, where many of Chicago’s most notable citizens are buried, these two tiny stones, one slightly tipped and more worn than the other, tell a sad story — but I don’t know what it is.

They’re found amid several generations of Marshall Fields and family. (The original Marshall Field founded the iconic Chicago store that is now a Macy’s.) I can’t say I’ve seen many, or maybe any, markers like them. Many infant markers have dates or a year and possibly a gender, if nothing else. These two, however, are “Baby.” Just “Baby.” Not even “Baby Girl” or “Baby Boy.” I have questions, many obvious. Someday I may dig for the answers.

• When were they born?
• When did they die?
• How did they die? Were they stillborn? Miscarriages? Tiny victims of birth defects or disease?
• What gender(s) were they?
• How are they related? Siblings? Cousins? Possibly twins?
• Who were the parents?
• Did the parents visit these minimalist markers?
• Finally, why did the parents or family leave such generic markers in a cemetery where vaults, obelisks, statues, and other hallmarks of fame and fortune abound?

While the Fields’ individual markers are fairly nondescript, their area is reigned over by this statue, behind a currently empty pool.

Who was “Baby”? And who was “Baby”?
