In 1861 census I have James and Anne Kewley 45 with children Betsey, Margaret, Catherine, Maria, Isabella, Mary Ama (Anne) Thomas and John in Eary Linne(?) German and it seemed to fit so I assumed Betsey was Elizabeth. In 1871 census I have Ann Kenley 55(wrongly transcribed - is actually Kewley) widow with Isabella and Mary A and a niece in German. In 1881 census I have Ann Kewley 64 mother-in-law resident with Henry Harris in Douglas.
I can send you what I have if you want. I have not looked at this in ages and some of it may be wrong so would be interested in what you think and what you have on Elizabeth and her descendants.
