In the 1871 census, there are two Catherine Boydes.
Number 1 is in Bride, b. K Michael, aged 12 and living with Ellen (30), John (35), Thomas E (4) and William H (7).
Number 2 is in Peel, b. K Michael, aged 14 and living with William (55), Mary (43), James (12)and William (16).
Number 1 shows as Catherine J. However this is probably an error as a Catherine Eleanor Boyde, daughter of John Boyde and Eleanor, was christened in Kirk Michael on July 24, 1859.
She is not recorded in the 1881 census but there is a child, Catherine C. Howland, b Bride, aged 1, living with John and Ellen.
