regarding this profile of Ernest Baker from Somerset, unfortunately I had mistakenly incorporated his "line" into my ancestry due to some erroneous information I had gleaned. I have since disconnected my tree from this one to avoid any further inadvertent contamination. My grandfather is still shrouded in mystery; I am waiting for replies from family members regarding the most likely candidate I can find. As such I am unable to offer any assistance regarding your questions about "twins" - sorry.
Good Hunting, Dave
