Kisha;

The Ellis Island site has several Jamaican Shirleys who came in earlier in the century, such as:

NAME RESIDENCE ARRIVED AGE BORN
Shirley,A. Alf. Swift River, Jamaica 1913 28 1885
Shirley,Adele Mercedes Kingston, Jamaica 1923 33 1890
Shirley,Arnold Hope Bay, Jamaica 1909 34 1875
Shirley,Beatrice Montego Bay, Jamaica 1912 38 1874
Shirley,Constance E. Kingston, Jamaica 1913 21 1892
Shirley,Edwin Spanish Town, Jamaica 1914 28 1886
Shirley,Eugenie Kingston, Jamaica 1921 25 1896
Shirley,Harold Kingston, Jamaica 1913 24 1889
Shirley,Henry Kingston, Jamaica 1913 24 1889
Shirley,Isiah Pt. Antonio, Jamaica 1912 27 1885
Shirley,John Wallbridge Kingston, Jamaica 1914 30 1884
Shirley,Lester Kingston, Jamaica 1913 21 1892
Shirley,Louise Swift River, Jamaica 1915 16 1899
Shirley,Sarah Swift River, Jamaica 1915 37 1878

There are also quite a few others that don't list a residence, yet whose ethnic origin is "African," (like those above).

You might want to take a look through the Ellis Island site for possible other family members. However, I think the "Searching Ellis Island Database in One Step" site is far easier to use, and I've put the URL below.

Happy hunting, "cuz."
