illigitimate child of Martin James Taylor

I am trying to identify whether there was a half sister to my grandmother and siblings. According to a great aunt this girl was called Pinky and was the daughter of Martin James Taylor and one of his wife's sisters. The wife and sister's surname was Hazen, so the little girl could have had Taylor, Hazen or another last name and born in either Florida or Georgia since the family lived in the Lake Butler,Fl area until about 1904 and then in Coffee county, GA. Does anyone have any input on this family story?
