Pal.gr.108

... etc. the analogy of the [forms] concerning hou?, both in Doric and Aeolic for you; and your possessives [derived] from hymōn [is] hymeteros. Of the third person, the nominative is hou; the genitive and dative [are] hou. In Ionic, [it is] eoika and sphe?; the plural [forms] of us, and both in Doric and Aeolic, etc., and from which [comes] hoi; and the possessives of them take the he and are said [to be] eoika and hee; the dual forms [are] sphōe and sphōin; the plural possessive [forms are] sphos, hos? once [used for] of that one, from where; for they always declined [them]; for example, besides sphōe, heōsphos from eō; and sphos in the genitive and dative; the nominative of the plurals is sphe [and] sphas; the genitive of the plurals is sphōn; the dative is sphisin; the accusatives [are] sphe [and] sphas. These then are the [matters] concerning the inflected [pronouns]; and from these, all four are possessives; from the genitive of the first person these are formed: ho emos, hē emē, to emon; but all [of these] do not have the article, but rather the [article] of the possession implied with them; declining with the possessions; for example, ho emos oikos (my house), tou emou oikou (of my house), tō? emō oikō (to my house), etc. And they follow... in the numbers he their cases. So that whenever it may be among the poets, tou emou pragmatos (of my affair), or any possessive from the pronouns; but when [it is] tōn pragmatōn emou (of the affairs of me), [the pronoun is] before the inflected word; for they are not of the same number. Either both the pronoun and the derivatives [are] in the same case. From the genitive of the second person [are] these: ho sos, hē sē, to son; which are also said poetically ho teos, hē teē, to teon. From the genitive of the third person [are] these: ho hos, hē hē, to hon; which are also called poetically ho heos, hē heē, to heon.
