Looking for info on the following family: William Dunn born circa 1821 in NY married Elvira young born circa 1824.They had a daughter Mary born circa 1845, Anna born March 19, 1849, Emily Elvira born 1850, and William born 1851. In the 1870 census, Elvira was a widow and living with her daughter Emily and son in law John Blake. Son William was also living with them. William Blake sr probably died between 1850 and 1870. Anyone reseraching this Dunn line? Thanks! Michele L.ockwoo.d
