William Acklin's son, Theo, predeceased him,so the heirs listed for William Acklin's estate include Theo's children. I was happy to find James V.A.Hinds on two Acklin related documents. No sign of James V.A.Hinds' mother or siblings [that would have been great], but these documents strengthen the Hinds/Acklin connection if just a bit.
