I don't know whether it is any connection but an ancestor of my husband, David Peacock
b.c1840 in Lanarkshire Scotland, and married to Anne Baird was a bit of a wanderer. He emigrated from Scotland some time after 1860 and spent time in NSW, Queensland and NZ, dying in Lithgow in 1924. However he had a son William John born Ipswich 1883, who later married Violet Amelia Brown in Sydney and had 3 children William b1911, Ferna b1912 and Elva b1917, possibly in Lithgow. However it occurred to me that David Peacock may have had relatives in the Ipswich area.
David did not stay there long as his wife had another child Isabella Jane (my husband's grandmother) in Christchurch NZ in 1885.
If you believe there may be a connection please let me know
