I am looking into the families listed above. I have much of the clinical data such as match hatch and despatch.

That said there are number of particular questions that I have where there are some interesting answers to be had.

I will reply to anyone who replies or has information. All my data is available in gedcom format.

To flesh things out;

Walliker (wallaker) Valentine immigrated ot Brisbane in 1880's from Hedleyhope Tow Law Yorkshire

Metcalf - South Australia around Port Elliot, then Wilmington

Barker - Hunter Valley NSW mid 1850's

Latham from Stoke on Trent

Kendall 1812 NSW then NZ. (I have much other information some of the branches including the infamous "Black Bob" Cooper)
