Make it possible to use exact date of birth when searching!
Almost all Swedes who moved to America changed their names, both the first name and the family name. Often they kept some connection to their Swedish name, but there were also persons who took completely new names. And even those who kept a connection did it in different ways: Some changed to an American name that was rather alike, some changed the spelling so their name would be correctly pronounced by English spoken persons, some who had a Swedish name with a meaning tried to translate it to English.
This means that when I in the Swedish administration books find that an ancestors of mine had siblings who emigrated, it is extremely hard to find them at Family Search. But there is one thing that could help the search: If it was possible to use the exact date of birth in a search it would be possible to find them. Of course you wont find them in the census, as they don't include date of birth, but you could find a death certificate where you could see what name they used in America, and then you could use that name for searching in census.
An exact date of birth in combination with "Sweden" as place of birth - but no name - would give a reasonable number of matches to look up.
