Saturday Night Genealogy Fun: Who Is Your Second-most Recent Unknown Ancestor?

This week's Saturday Night Genealotgy Fun challenge is a rather logical extrapolation of a previous one.

Here is your assignment, if you choose to play along (cue the Mission:  Impossible! music, please!):

(1) Who is Your SMRUA — your Second Most Recent Unknown Ancestor?  The one that you don't have a name for, or any information.  The one completely unknown to you.  

(2) Have you looked at your research files for this unknown person recently?  Why don't you scan it again just to see if there's something you have missed? 

(3) What online or offline resources might you search that might help identify your SMRUA?  What about DNA matches?

(4) Tell us about him or her, and your answers to (2) and (3) above, in a blog post, in a comment to this post, or in a comment on Facebook or Google+. 

NOTE:  We've done Most Recent Unknown Ancestors before.  Feel free to work down your list to someone you haven't written about before.

Here's mine.

I have written previously about my Most Recent Unknown Ancestor, which is my paternal grandfather's biological father.  I have found two close Y-DNA matches to my father, which have led me to the hypothesis that my biological great-grandfather was a Mr. Mundy.

When I looked through my family tree, I was surprised to see that my second-most recent unknown ancestor is . . . Mr. Mundy's father, my great-great-grandfather!  Yes, even though I am Jewish on my mother's side, I have at least a given name for every one of my great-great-grandparents on that side, and I have complete names for most of them, as well as for everyone on my paternal grandmother's line.

Obviously, finding my great-great-grandfather's name is entirely dependent on identifying my great-grandfather first.  I guess this challenge is a hint that I really should get back to working on tracing those Mundy lines backward and then forward in time, so I can try to find some living Mundy descendants with whom to communicate.  Maybe I will be lucky enough to find one or more who have already done autosomal DNA testing, so I can try to confirm my hypothesis that Bertram Mundy was my grandfather's biological father.

Like I always say, hope springs eternal!
