Julie, With a name like Wills, there are probably dozens of possibilities. I'm wondering when and where they arrived in Australia. If they migrated shortly after a marriage around 1837, all the census records in the world won't find them. You've really given us few actual facts. You're saying general things like married around 1837, came to somewhere in Australia, two sons died young. You really need to be telling us specific names, dates and locations for each of these events. I find it hard to get motivated to help, if there's little sign of effort Peter
