Thanks for your second message, grateful for your help. Yes I have seen the Patron entry for Letitia, a few years ago the address of the Patron was on the site and I corresponded with him, his wife was Letitia's daughter from her second marriage. He sent me a lot of information which he had put on the LDS site, most of it completely wrong, when I wrote back to him (very diplomatically) pointing out his errors I never heard from him again ! But, I have just written him a letter asking if he has Letitia's birth. cert from 1854 so will let you know ! I have spent hours on the 1861 and the 1837 site looking for her and have now decided enough is enough - she obviously doesn't want to be found, it's very difficult as her age changes quite a bit. 1868 on marriage she was 19, 1871 she was 20, 1881 27, 1886 on second marriage 32, 1891 37, 1901 47 and if the Patron entry for her death in 1925 is to be believed 75.
I notice that you live in Australia - if you ever come across a Joseph Whitfield born 1848 Workington, Cumberland to a John and Mary Whitfield (nee Beeby) please remember me ! He was Letitia's first husband (they were married Workington 1868), they are together on the 1871 census but she is living with another Whitfield with a small family on the 1881 and Joseph is nowhere to be found, nor can I find a death. I know he was around 1875 as the eldest child living with Letitia on the 1881 is his son. He had a brother William in Australia so I suspect joined him but my efforts to find him in Australia have also failed.
If you don't have all the census for England I have a sub. to Ancestry so happy to help you out.
Kind regards, Pauline
