Hi Carolyn,
I don't add people until I have solid sources to do so. If I can't add them with birth/census/marriage something to prove their existence and relationship, I don't add! Unfortunately I haven't researched those enough yet. I'll get there though, one day! So many family, so little time. I wish I'd gotten into genealogy back in my 20s!
His siblings are all in there as well as about half of his children...it's just getting THEIR lines nailed down that is the user of time. :D
