I found this message on the 'Allens - Nottinghamshire' forum at Genealogy.com

Looking for descendants of John Allen and Emily Whitbread. They had been living in Carlton, Nottinghamshire in 1915+. One of their daughters was named Zillah, after her grandmother on the paternal side.

This is almost certainly a reference to Ziller (Zillah) JACKLIN (née ALLEN). I have replied to the given email address, just hope it is still 'live'.
