Looking over my paperwork for the Ziselman family in Okolov/Akalova in the 1850s (>from the revision census list) I notice the name a of a relative living with the family, and who is called Hirshe Nokhomovitch Shilevich. He was born in 1809 and died in 1844. He is listed together with Aron Abramovitch Raskind, who also lived with the Ziselmans.
Does this ring a bell to anyone? Was it ever a practice for some older "relative" to be listed as living with someone and for some reason they weren't really a relative? Also, why did revision lists list the name of someone who had died years before?
