Hi kay! What's the name of your family history program?
You're right - it's an ever-expanding universe - to connect 2 of our shared interests...
I focus on my direct line....if I come across the names of brothers and sisters, I note them, and record them, but I don't go looking for them necessarily..except for say...about 4 generations back or so. LOL! Hope this helps...I did understand your question, I think.
