Searcing for Rose and Anton Pearsons family !

I am searcing for Rose and Anton Pearsons family. I know they lived in Vanderbilt Ave. N.Y and had 3 children, Hazel b.1913, Athur b.1928 and Elenor b. 1924 due 1930 census. Rose (Benny her christian name) emigrated from Lillisand or V. Moland in 1903 and was my grandma`s sister. Would much appreciate if someone had something to tell me about theese people, if sons or daughters is living. Thanks, Thorbjorn
