Well some progress on the Farrar side of the Dunn line: as Uncle Bud noted in his email, his grandmother Catherine (Creegan) Farrar, was the daughter of Lawrence and Margaret Creegan, both of whom were born in Ireland. It will be interesting to see where that trail leads.
Catherine’s husband, Daniel Farrar, arrived in this country in 1860, according to the 1900 Census. That form listed his birth year as about 1836 in England. I happened to find a Daniel Farrar who matched that birth year listed in the 1851 British census, in Leeds, the son of Samuel and Phoebe, both born in 1808. It seemed promising when he turned up missing from the family’s entry in the 1861 census. Unfortunately, it seems that this Daniel Farrar didn’t emigrate to Rhode Island, but rather just down the road. I eventually found him as the head of his own household in Leeds, with a wife and a daughter named Phoebe. Oh well.
