Gresham Grisham Grissom and Other Spellings

My Grisham family is sketchy and I am trying to sort through the many who were around in the early 1800' I have proof bacck to Hartwell Grisham near Franklin in Williamson County TN great-grandfather. in 1840. He was my gggreat-grandfather an my grandmother' great-grand father. most all records for him used the Grisham spelling but those for his children were later spelled Gresham. I have also been told there were relatives in middle TN who also used the Grissom spelling.

Anyway this line (I will creat new journals for them) includes the following surnames:

Leeds, Ormes, Buttery, Gotto, Montgomery and some others.
