I've hit a wall on my White search. I have mother Ann/Anna White (b. 1840), sons William C (b. 1863), Samuel (b. 1874), Robert (b. 1877), daughters Elizabeth (b. 1882) and Anna (unknown birth date) all born in Northern Ireland. William came to America first sometime between 1885 and 1889 and settled in Chicago, Illinois. He worked to bring his family to America by around 1895. He married Mabel Collins in 1899 and they had 5 children: William Collins, Theodore, Grace Muriel, Roger and Marjorie. I'm looking for mother Anna's maiden name, the name of her husband, actual US arrival dates..... thanks in advance!
