Marlyn Lewis gives Emeline the surname of Heron (several other posts to SGM do the same)--and I have add Walter as her father. However, CP states that this Emmeline is often confused by Emmeline's granddaughter (daughter of Alice) also named Emmeline who married John Darcy. Even though the Heron families are different, the fact that both fathers are named Walter Heron is quite a coincidence--perhaps too big.
