What happened to Booth after the manhunt

[RJNorton]

I do not recall what book I read this in, but I once read that there were at least 5 alleged Booth skulls and "mummified remains" making the rounds of sideshows and county fairs in the USA. This would be c.1920's-1950's. Possibly this information was in C. Wyatt Evans' book, but my memory is too foggy to be sure.
