I was just searching the interenet and found your family tree for the McKee family.
In your 13th generation you have Ella (Alvira Alee) with her three marriages.
Her third marriage you have to and Unknow Sellon. I would like to inform you that it was Henry Latrobe Sellon b. 23 Nov 1845 in Lynn Twsp, Knox, Ill. d. 15 Apr 123 Hardy Sharp, Arkansas. he is BU in Big Piney, Sublette, Wyoming (Named after family relative Benjan Henry Latrobe)
Henry was living in Ft. Bridger, WY when he lost his wife
I do not know where or when he met Ella - I would like to find this out - but he left Wyoming because his two daughters did not approve of his marriage. So he and Ella either went o Hardy, AK or they may have meet there. It just seems more probable that they went together. My father (Rev. Henry Lyon Sellon) was living with the couple when his grandfather, Henry Latrobe, had a heart attack.
Henry's two daughters came to AK and from the paper work I found rather "cleaned out the house" and I am affraid were not very nice to Ella. They practially left her with nothing - probly what Henry was affraid of. They took Henry's body and his grandson back to Wyoming and I had no idea what happened to Ella - but from what I have found out since she must have moved to California where she died.
Anyinbe know the fate of her daughtr Algie Fraces Brooks???
