Hello
I can't help you very much as the name Skitt means nothing to me. However, I do know that Richard Warren married Ann Loxdale, 16 Dec 1759 at St Mary, Stafford, England and they had five children, none of them called Elizabeth.
But, Elizabeth Warren knew Joseph Loxdale Warren. She (possibly eloped with and) married Thomas Morris of Ribbesford, Worc on 2 Mar 1782 at St Peter Cornhill, London. He was the son of Mary Cheeke and Thomas Morris, and he was christened 23 Apr 1762. Apparently in the Royal Navy he was buried in a garden at Port Antonio (Jamaica?). Before that they had three children: Samuel Cheeke (chr 23 Feb 1783 - 25 Jan 1839) who married Sarah and had one son Samuel (maybe also some daughters),
Elizabeth (bpt 29 June 1785 - 31 Dec 1838) who married John Massey, and
Joseph (chr 7 Jan 1787 - ??)
Elizabeth Warren/Morris married secondly Robert Meek on 15 Dec 1791 and had three more sons.
Samuel Cheeke Morris inherited the property of his grandmother Mary Cheeke/Morris.
Elizabeth Morris and John Massey (my 3x great-grandparents) have descendants in four generations with the name Loxdale as a Christian name.
It is through the Cheeke family that I was able to trace a very circuitous route back to William the Conqueror and his wife Matilda who was descended from Charlemagne, King of the Franks.
The information I have given you comes mainly from familysearch.org
If you Google Shropshire Archives and key in Samuel Cheeke Morris, Loxdale etc, you will find more information. Likewise Staffordshire Archives, etc. And if you do find a connection to the Morris and Cheeke families I will happily give you some more information about them.
I would be very interested to know exactly what John Skitt's Will said in regard to Loxdale, as this might help me to solve that mystery.
Cheers,
Alpha
