I have been speaking Pig-Latin since a babe in the crib! ALL my family speaks it also! It is like a second language at our reunions, etc. My daughter (now 18 yrs of age) picked it up on her own just by listening to the rest of us. I guess that's how we all learned it in my family.
ANYWAY...Here is what I was able to find out for you. Hope it helps...Tamara

Pig Latin,
or sometimes called Dog Latin. It apparently goes back at least to
mid-18th century England, and was at first a combination of Latin (or
Greek) and English. Hendrickson, Robert 1987 "The Henry Holt
