Hi Folks, Thought I'd share this one as even PROV wasn't aware that this search option worked ... I was researching James HARRISON (not of Geelong Advertiser fame) who married Margaret BYRON in 1855 at St Mary's, Geelong. When they married, one of the witnesses was Bridget BYRON, believed to have been Margaret's sister and believed that they came to Australia together from Co Tipperary. Previously I would try to find Margaret BYRON arriving, hopefully the right age and country of origin, then check that ship's passengers for her sister. I hadn't got very far until I tried this search option ... Family Name = Byr* Given Name = Bri* OR Mar* Year to = 1855 Primary Sort = Year Secondary Sort = Ship And there they were - right next to each other on the list - arriving at Point Henry in June 1854 on the ship Chandernagore. The surname was indexed as BYRANE but they were from Co Tipperary and the right ages. And an even more positive match - Bridget was assigned to John ULMER of Corio Street, Geelong - they were married in 1857 and both Bridget and Margaret had the same parents listed when they died. So the Boolean expression "OR" works on both assisted and unassisted immigrants indexes on the PROV web site. You must put the OR in capitals. This is the only Boolean expression that works (NOT doesn't, but AND is the default for a space). Just think of some of the options you can use - if you know a family arrived with a bundle of children and know the names of the children (i.e. Sarah, Patrick, Michael, Mary), try Given Name with something like ... Sar* OR Pat* OR Mich* OR Mar* And be sure to use the sort by Year and Ship and you'll find they'll all be grouped together. I think it would probably work better with the children than the parents but of course you can try the parents as well - it's just that children names are often in full but parents are sometimes just an initial. Bottom line - this opens up a whole new option for finding arrivals of ancestors that was sometimes more difficult before. Have fun ......... Susie Z
