If it looks like a duck...

So is it just me, or does this not resemble a duck? Or have I just been spending too much time looking for waterfowl?

Back to our story:

Husband #2 was born in 1888 in Missouri to a German father and American mother. In the 1910 census he is with wife #1 in Oklahoma where son #1 would follow in that same year. Son #2 shows up in 1912. By 1920, the four of them are in Wyoming where presumably he's become employed in the oil industry. Here is where the fates collide. Until early this week I didn't know where wife #1 went, if she lived, died or disappeared. I know that Husband #2 married my great aunt in 1926, but that didn't tell me where wife #1 went. Finally I dug up gold on www.findagrave.com. I had been looking for her in Wyoming, with her married name, and I finally put in her maiden name. Bingo. A photo of her headstone where she is buried with her mom and dad in Missouri under her maiden name. But why? She didn't die in Missouri or there would be a death certificate available. I don't know if she died in Wyoming yet. Interestingly enough, her mother died in the same year, and there is no Missouri death certificate for her either. None of their other children are on the headstone, why just her? Why didn't she remain with her husband and children?
