Have just found a Will (written Nov.1911) for William Gilmour, Belfast which mentions 2 grand-daughters Matilda Roberts and Kathleen Roberts of Brooklyn U.S.A. After searching Irish indexes for possible parents I found a marriage for Margaret Gilmour and William Roberts (William Gilmour did have a daughter Margaret Jane born 11 Sept.1865). Then found 2 possible births in Belfast: Matilda Roberts 1888 and Kathleen Jane Anderson 1890.
Next found passenger list which seems to match the family: 1 June 1892 "Siberian" arrived N.Y. from Moville, Ireland: William Roberts 26 clerk, Mrs. Roberts 24 wife, Tillie Roberts 3 child, Kathleen Robert 1 1/2 child.
1900 census confirms I have the correct family- Manor Rd., Richmond, N.Y. (Staten Island):
William Roberts, June 1865, Ire., to US 1892 Na, Handkerchief Mfg.
Margrite Roberts, Sept.1870*, England*, m.12 yrs 2 ch./2 living
Tillie Roberts, July 1889, N.Y.*
Catheleen Roberts, June 1891, N.Y.*
brother-in-law John Gilmor, Mar.1868, Ire., single, to US 1899 alien, laborer
+ 2 servants
* Margaret's year of birth and place are wrong, also, children born in Ireland not N.Y.
Margaret's brother Anthony Gilmour was superintendent of Handkerchief factory in Staten Island so William Roberts was possibly working in the same place (Anthony lived at Manor Rd., New Brighton- I've found him and family in U.S. census records).
Since the 2 girls were alive in 1911 they should be listed in 1910 census but I've not been able to spot them there (or in later ones although they could have married after 1911). Have also searched Italian Genealogy website for possible marriages and deaths without seeing anything that looks likely.
Would appreciate if anyone can find them in 1910 census or any other information on the family.
