My chain migrants were during the 1880s/early 90s from France; 1st was eldest child Françoise Joséphine Gonella leaving France as a maid with a family going to America in 1884; no passenger list or immigration entry found (since she was a servant it's attached to her employer's record, and we don't know those).
2 years later "Fanchette" marries in Washington DC and her 2nd brother Joseph arrives in New York City. 1/
