Just put in a couple more generations and I've learned a valuable lesson:
There is NO WAY this tree could have been completed without personal information from an ancestor. So far there are family members born in Scotland, several English counties, Falkland Islands, India, Sri Lanka, South Africa, Bermuda, Egypt and Ireland. One of them spent several years at sea in the Arctic, and there were no records during that period. Some of them finished their days in Canada, and one died in Argentina.
Please, please do talk to older people and get their stories.
