On the 1930 Census of Monroe Co. Ohio there is the following:
Leslie O. Carpenter, 29, married, 23 at 1st marriage, b. Oh, Oh, Oh
teacher, public schools
Leata D, wife, 22, married, 16 at 1st marriage, b. Oh, Oh, Oh
Sarah L dau, 5
Margaret E dau, 3
Betty R dau, 1 7/12
In 1920 he is living with his uncle and family:
Snyder, Charles C, head, 32
Maggie L , sister, 36
Eliza E, mother, 71
Carpenter, Leslie O, nephew, 19
Bunting, Elijah M, brother, 52
In 1910 he is with his grandmother:
Eliza Snyder, head
Margaret Snyder, dau
Charles Snyder, son
Carpenter, Orion, grandson
Bunting, McCleden, son
Could this be your Leslie? Monroe County is in the southeast part of the state and is on the Ohio River. If he ran away with Leata, they could have easily crossed into either Pennsylvania or West Virginia. I know WVA has had very liberal marriage laws. If she wasn't of legal age to marry in Ohio, they may have run off to another state and when they returned, her parents may have prosecuted him. -----Genealiza
