Elizabeth/Leah were sisters, both married Peter Acker
They are the daughters of John VOWELL b 13 May 1800 SC and Elizabeth STERGALL b July 1808, mar + - 1825. Elizabeth b 1831, Leah b 1833. When Elizabeth died, Peter ACKER married his sister in law Leah. Hope this settles some some confusion. John and Elizabeth were my GG Grandparents via William their first born. Have much on this VOWELL family, happy to share.
