53 bicycles: A lateral thinking puzzle

Seems pretty straightforward. Her father was of Jewish ancestry but he was either ignorant of that or he had been hiding it from everyone. Possibly something to do with WW2.

No.

Yes.

Yes.

You have grasped the essentials of the puzzle, but there is still a very specific answer that requires lateral thinking. The answer has nothing to do with WW2.

A line questioning I didn’t see asked. (Forgive me if I missed it).

Is her biological father the same as the man she actually called father?
Did her mother have an affair with a Jewish person?
If not, did she in any other manner have sex with a Jewish person who was not her husband?
Was there an identity mix-up?

A different direction, if the above thinking is wrong:
Were her paternal grandparents Jewish?
Did they know they were Jewish?
Did anyone else in the family who would have been living when the father was born?

Also, is Ancestry.com relevant, other than saying it happened fairly recently?

Yes.

No.

No.

Yes.

Yes.

Yes.

Yes.

No.

Was her father switched at birth at the hospital with a Jewish child?

Her father was the Jewish child, but you’ve basically got it.

It’s an absolutely fantastic true story. An Irish child and a Jewish child born in the same hospital, on the same day, delivered by the same doctor, with sequential birth certificates one number apart. They were sent home with the wrong parents, and lived their entire lives in the wrong families. They died without learning the truth.

If the Jewish man’s daughter (who was raised as an Irish Catholic) hadn’t done an Ancestry DNA test, and persisted until she found out the truth, no one would ever have known. It makes you wonder how many other people are walking around with the wrong identity.

**Back in the late twentieth century there was a rock music festival held several times in honor of a certain event. On each of these occasions, numerous bands would play energetically for increasingly larger and livelier crowds of merrymaking music, dance and party lovers.

But looking back at the history of the festival (an event which alas is no more), I notice that among the list of many well-known, lesser-known and frankly obscure rock groups involved, there was among them one band who was there every single time — but whose members* never* played a note or sang a song for the festival. How come?**

Were the band all dead? Or some of them?

Did the event take place at or near their graves?

Were the members of the band there before the band was formed?

No to both.

No.

Was this a “band” as in the sense of a musical band?

No.

Was it a band of people?

No

Is the “band” a group of any organisms?
Is the “band” a group of discrete objects?
Is the “band” a non-counted quantity of substance?
Is the “band” made out of rubber?

Is the “band” related to the event which the festival was held in commemoration of?
Would knowing what the event being commemorated was help?

Is the band an inanimate object?

Is it made out of :

  • fabric/ cloth ?
  • metal ?
  • plastic ?
  • elastic?
  • paper?

Is the band a group of living beings?
