Harry, you wrote:

"In 1861 Elizabeth was widowed, working as a cook in Birkenhead.
Mary Ann & John Thomas are living with their aunt, Jane Kelly in Onchan.
The where-abouts of the other three children is not known. "

I can't find Eliza Jane or Robert in 1861, but I think that this may be William:

1861

5 Walters Court

Name Age
Bridget Hartily 40
John James Hartily 1
William Tongwend 14

WT 14 is an errand boy, lodger, b IOM
