I won't pretend to know why anyone would name brothers Abe and Jeff, but I will offer a few observations:
- In most cases, the children were born after 1865, suggesting that parents, rather than slaveowners, may have chosen these names.
- In those cases where one of the brothers was born during the war, it is always Jeff, not Abe.
- This pattern does not seem to be peculiar to any particular state, but it does seem to be limited to newly freed slaves in the ex-Confederate South.
I can only suggest one political motivation that makes some sense:
I remember once reading a WPA slave narrative (admittedly, not the very best source) in which an elderly ex-slave characterized Lincoln and Davis as partners in bringing about the war that brought on freedom. He didn't distinguish between their motives — he argued that their quarrel created the necessary conditions for emancipation. If that was a wide-spread idea, it might account for the Abe-Jeff pairs.
