duggan on Family Tree Circles

My GGG grandfather was James Barrett. He had two sons, James and Alfred. (Possibly others). Alfred married Catherina Duggan on 2 August 1844 (to be confirmed) and fathered my Great Grandfather Augustus Remy Barrett (probably sometime between 1845 and 1855). Augustus Remy Barrett had two brothers George and Henry who were both Ordained RC Priests. We believe there were also other brothers and at least one sister. Augustus Remy Barrett married Frances Day (year unknown) and moved to South Africa. Had eight children including Kate (Spinster) Cecil, Francis (Spinster), Remy and others. My Grandfather Eustace Duggan Barrett was the youngest (born 26 July 1897 in Somerset East, South Africa).

If you have any information or you find your family tree overlaps with this I would be very interested in exchanging notes
