A word for “ancestor” in the Gnomish Lexicon Slips of the 1910s with variants eithog or eithweg, and an original meaning of “†father, sire” (PE13/113). Tolkien indicated the variant eithog was derived from ᴱ✶attū + ōka, where the first element clearly means “father” and the second element is probably some kind of ancient masculine or agental suffix because (a) that is consistent with G. -weg in the other variant and (b) G. -og was often an agental suffix in the Gnomish Lexicon. However, it is not at all clear how ᴱ✶attū became eith-.
