descendants of Emily Christopher Callighan?

 Nurse midwife Billey at Ann's Grove 1940s -1952 is perhaps a niece of Ella Butt-Up Europe, Nelly Mackie, Ms Seymour, Mary Chichester and Irene Graham. Perhaps, Muriel Grant is also their niece, Perhaps, Billey at Bush corner and Buxton are their relatives. Josephine Patterson, Harold Lutchman and Elvis Trotman are my sources of information. Harold and Elvis cannot remember the names of their grandmother's siblings who resided at Mahaica and Mahaicony. This researcher also thinks a sister Rosalind Seymour, resided at Noot-en-zuil and later at Victoria. How about Ms, Nelson mother of Wendell Pieters, and at least a daughter and another son? Memory is fading. This warrior can't recall the names of Wendell's siblings. Who are family historians of the descendants of the daughters of Emily Christopher Callighan? Please facilitate links between them and this researcher – soonest. Thank you.
