What exactly is the nature of the connection between the 'Bahamian' Emma & Ada and Jacob H. Webb?

I can save you some time on the sisters in the Brady Studio images at least: Ada and Emma Webb

“WEBB, SISTERS THE. – Emma was born in New Orleans, La., June 18, 1843. Made her debut in New Orleans, as Julianna in the “Honeymoon.” Ada was born in New Orleans, Sept. 18, 1845. Made her debut in “Grandfather Whitehead,” playing the Child, at Placide's Varieties, New Orleans. Ada soon after joined Marsh Troupe. In 1858 the sisters gave drawing-room entertainments with their mother. Visited California in 1859, and played through the mountain towns and cities. Opened in New York, Jan 9, 1860, at the Old Bowery Theatre, in the comic drama of “Boys and Girls of the Present Day,” Emma appearing as Fanny, and Ada as Kitty. Went to England in 1867, and opened at the Olympic, London, Aug. 14, 1867, in “Fanchon,” altered to “The Grasshopper.” Revisited California in Dec, 1867, and returned to New York in June, 1868. Emma then quite the dramatic profession and turned her attention to lecturing, while Ada continued starring. Ada married in Brooklyn, N.Y., on Aug. 17, 1869 to W.M. Connor, and retired from the stage.”

Ada Laura Webb Connor

I think the Bahamian appearances might just also be the American duo. Were there any other seasons besides '63?
