Just a question or two:
Did Bridget die quite young? And Thomas re-marry?
Did Thomas emigrate? And possibly re-marry?
- because (and I know this isn't any promise of veracity) there are several online trees that seem to send him off to the antipodes, and a marriage there....
I can't find an 1861 census ... yet....
After the birth of my great grandfather Hiram Greenwood in 1846 in Hulme, and a possible younger brother James W (although Hiram is listed as "James Hiram" on the 1871 census), and the 1851 census showing Thomas Greenwood age 32, Bridget age 28, Hiram 4 and James W 3, and Betsy Ward 23 and John Ward 14 living in the parish of St Marks, Hulme,Chorlton......
.after the 1851 census Thomas and Bridget both seem to totally disappear.Hiram was baptised 25th October 1846 Cathedral Manchester. I don't know whether Cathedral refers to the area of Manchester, or the church where he was baptised, but because his mother was Irish it was probably in a Catholic church.
I just found something today that might be Thomas Greenwood, Hiram's father. The 1871 census has a Thomas Greenwood, age 52, born about 1819 in "Hepden" (sic) Bridge, Yorkshire, living in Manchester, ecclesiastical parish "Cathedral", sub-registration district Market Street, with Anne Greenwood, age 40, and three other people. Thomas and Anne Greenwood are shown as lodgers, Anne was born in Manchester. The Head is Elizabeth Hamilton, age 60, shopkeeper. Thomas Greenwood's job is listed as "Card Dealer". The census area is "Collegiate", Manchester, and the address is 63 Long Millgate
The 1871 census shows Hiram and Mary Ann Greenwood living in the parish of St Stephan, civil parish of Salford. I find it significant that Hiram gives his place of birth as Manchester, but the place of birth of his two daughters Rebecca and Mary Ellen as Salford. (Mary Ann was born in Dublin, Ireland).
