I'm sure you're right. I haven't looked very closely at Thomas and Mary's children as I haven't fully pinned down that they are the right couple. I gave the names in cae they were called after grandparents etc
When Mary Ann Barratt married Thomas Wright in 1845 she gave her father as Joseph Wright, weaver, and censuses consistently give her birth as 1826/7 in Manchester. There is a Mary Ann d Joseph and Margaret B in 1825 but that Joseph is a carter, whereas the marriage between Joseph Barratt and Judith/Julia Ann Sweeny gives him as a weaver. In addition, Mary Ann named a daughter Selina (not a particularly common name), as did Joseph/Julia, so the evidence is quite strong that the Joseph/Julia pair are the right ones. Except that I can't find a baptism for Mary Ann...
Just to complicate issues, in 1871, a Sarah Barratt, 74, widow, is named as Thomas Wright's mother-in-law (ie Mary Ann's mother), even though her husband appears to be living in the workhouse. Putting Judith instead of Julia on an entry might just be a slip, but putting Sarah seems very odd, unless it is a second marriage.
