Thank you for your replies, I will answer as I can.
Jim1 is correct in identifying Ethel's birth. Ethel was born on 16 Nov 1875. We have her birth cert.
Jonathan PELL & Kate ANDREWS married on 27 Apr 1875, at Pimlico, MDX. So Ethel was born abt 7mths after their marriage.
Jonathan PELL had multiple occupations. He leased a farm called 'Glanystwyth' from the Earl of Lisburne - but we understand he sub leased it. (However, there are newspaper reports of him winning prizes for cattle in the local show.) He also leased the Royal Belle Vue Hotel in Aberystwyth from the Earl. He was proprietor/manager of the Royal Belle Vue Hotel from 1864 until at least December 1873. (His father-in-law was the previous proprietor) He was also director, chairman and/or company secretary of several mines near Aberystwyth. The mining interests appear to dominate in the early 1860s and late 1870s. He was born in the parish of Weston Favell in Northamptonshire in 1833. He appears to have arrived in AberystWyth Wales in 1856 and remained there until his death in 1884.
Jonathan's first wife, Sarah MARSHALL, died of apoplexy on 25 Dec 1873. newspaper reports of her death do not make any reference to a child.
It appears the Jonathan & Kate have separated by 1881 - they are living at different addresses in the census. Frank PELL is with Kate and Ethel living in Alrewas, Stafford, England
