Margret,
I have the birth of Frances Mary as being Ireland, 1877. (Dublin South Vol 12 pg 627 FHL# 101054) This is given on the 1881 Census at Lambeth. She arrived in the US about 1886, three years after her parents did, staying with them until 1894, the year they both passed from long-endured illnesses. She married Llewellyn Huston 24 Sept 1908 at nearby Newton MA. She passed away from Chorio Epithelioma 2 April of 1909. I am not sure if she had any children.
Francis Patrick J was born Sept 20 1880 at Lambeth (Q4 Lambeth Id 378). He was naturalized in the US 1901, registered from Chicago for the WW1 draft, and was married at 5 Feb 1944 to Louise Buhmeier Weight. I do not have a date of death, though they show up in 1950s in Memphis.
