Someone has been working on an enormous Newman one name study, which has over 16,000 people with the last name of Newman. The site lists only one Kilner -- Kilner Peacock Newman, born in Dec. 1848, in Listowel, County Kerry, Ireland. His parents are Thomas Newman, 1807-1855, and Mary Anne Peacocke, 1819 - 1870, both of the same town.
No new revelations to be gotten from this, I think. But hey, if you're collecting Kilner Newmans, you want to be sure you catch them all.
