Hello Angio
Ingy was my Mother's first cousin. Her Father, Johnny Othea Boswell was her aunt Rhodie's sister. 
We have a photo of Ingy and a brother who might have been called Edicar after his dad. 
Lavina Boswell was my great grandad. I have a photo of him too. 
He was named after his grandad, Salvaino. 
Eric Trudgill has produced a pamphlet on the whole family. 
Mom told us that when duckering. I.e. Fortune telling, Rhoda would ask that the client bring in a white shirt for luck. 
It was because Uncle Edicar liked a white shirt. 
The family also used the names boss, and Sherrif. 
Hope this helps. 
Vince
