Tricia, Yes, I would really appreciate any photos on Younkins that you might have for my records. Unfortunately, I don't have any info on your Harriet or her family. My Younkins line has been difficult to connect so have focused on my direct line and not really on the extended lines. I'll hang on to your email address in case I run across anything that you'd be interested in. Your Harriet and my 2 greats grandmother, Malinda, would have been sister in laws, so you never know.
Have you obtained William's Civil War records? They may have info about Harriet in them if she applied for any pension rights that she may have had. I've had great luck with Civil War records.....lots of surprising info in many cases.
