Dear Simon, Thanks for your reply. I would be very happy to exchange information on the various families with you though I'm still discovering more details daily myself.
I have gathered some information on Edward Partington & his family & would be glad to compare this with you & share what I know about the Barlows.
Regarding the summary you posted, I believe Edward was born in 1836 & Emma in 1838 (from Parish Records on the IGI). Rachel was also Sarah's daughter - members of her family were still in touch with mine in the 1970's.
Sarah herself is on the 1891 Census under Sally Barlow, living with daughter Mary in Heap. I have found the death of a Sally Barlow in 1893 aged 77, rather than 1889.
Emma is the Mrs.Horrocks you mention, married to Thomas. Alice is Mrs.Moore, also married to a Thomas. Betsy was married to James Lomax & died in 1910, I believe. Mary wasn't married in 1901 & died around 1916/17. John I have only traced to 1871 Census aged 21 so far.
My email address is firstname.lastname@example.org. Please get in touch to discuss this further.
