Good evening,
I have the GRO records!
Charley and Henry Minns
These are two twins born on the 28th March 1866 in Winning, Newburn, Northumberland, England. They are the sons of Thomas Hills and Eliza (foremerly Minns).
They are most likely not related to my family line, but part of my does wonder if there was an issue with surnames. Thomas Hills may be Thomas Kelly, and Eliza Minns may be Eliza Maloney. Perhaps a reach too far... I've not been able to locate either boy on later census, nor death records. And there is similarly nothing for a marriage Hills/Minns marriage record.
Sarah Bridget Kelly
This looks to be correct, Sarah Bridget is the daughter of Thomas Kelly and Eliza Maloney. Born in October 1867, Newsham, Blyth.
Matthew/Mark Kelly
I also did some digging for the eldest boy, Matthew, listed as a son of Thomas and Eliza. According to the 1871 census and his death record, he was born in Thornley in 1864. Interestingly, i found no record for a Matthew Kelly - but two GRO records for a Mark Kelly born in Thornley in 1864.
One Mark was born on the 24th September 1864 to a Matthew Kelly and Eliza Maloney (birth registered 29th September 1864). The second Mark was born on the 26th September 1864 to a Mark Kelly and Eliza Maloney (birth registered 2nd November 1864).... Not sure what this means, a clerical error?
I have a marriage certificate from 1863 for a Matthew Kelly and Eliza Maloney in Co. Durham. Mark is listed as being 16 years old than Eliza, so this definitely isn't a case of Thomas using a different/middle name.
Be interesting to hear all your thoughts on these new clues! I'm happy to post the birth records if of use/interest.
