here is a fun website to spend some time on, also introduced to me by my friend kim:
through it i have discovered that i have common ancestors with joseph smith, brigham young, wilford woodruff, parley p pratt, heber c kimball, eliza r snow, and many others. brock also has common ancestors, different from mine, with all of the above plus emma hale smith, mary fielding smith, elijah fordam, and others.
plus, i have found more than one family connection to most of the above, because although they didn't know it at the time, they were all related to each other. so our children are related to most of the above in more than one way.
so far all of my connections have come through my great grandfather roland woodruff fish, and all of brock's have come through his great grandfather david fisk stout.
type in your name and your parents' names, and it will show you early saints that you are related to, and just how you are connected, from the common ancestor on down to you. i thought that i knew quite a bit about my ancestry, but this is all new to me.
i have felt my ancestors with me here in nauvoo, something i hadn't anticipated, and i am grateful.
