surname barrow

[anne addy]

I have started my "Barrow" family tree and all I have to go on is my
g-great grandfather's name was Samuel John Barrow b.1846 Finsbury.London.
Can you help me and possibly parents names, and siblings.The family sailed to
Australia in the 1860's ,then to Tasmania and finally here to New Zealand,
just a shot in the dark but gives me more to go on reasearching. Samuels
brother was named William, and Samuels father also a Samuel.
