Ina Alleyne-Prescod has developed a family tree site for the descendants of Samuel and Katherine Johnson of Grenada.
Here are some of the surnames it covers:
Alexander
Alleyne
Boles
Brathwaite
Buckmire
Bullen
Callendar
Caton
Fletcher
Johnson
Lewis
Marryshow
Prescod
Regis
Radix
Small
Taylor
Wells
So, far the tree is fullest in recent generations, though the information for the Johnson branch of the family is richer than for other branches. If you find that she is a relation, she would probably welcome your help in fleshing things out and going back further in time.
