There are two ways to find relationships between people, under the
1) The "Relationship With...", found on the His / Her menu when viewing anyone's page, is used to determine the relationship between any two people on the website, even from different researchers.
This finds grandparents, grandchildren, aunts / uncles, nieces / nephews, and cousins up to 35 generations apart. It does not find in-laws.
2) "Relationship Lists" shows a list of aunts and uncles, great aunts and uncles, or 1st, 2nd, or 3rd cousins for the current person.
For each person listed is an image (hover the image to see the full size), name, birthdate, birthplace, spouses, and avatar for the researcher who posted.
As always, if you see blanks for the birthdate, birthplace, or spouses, go back and try to fill them in wherever possible.
