“Possessed of her right mind”

So The Legal Genealogist was poking around in obscure records again and ran across Mary Louisa Hess of Yamhill County, Oregon. And what a woman she was! And what a sad state of affairs she had to confront just before the end of her long life.

She was born Mary Louisa Kaiser — the spelling is given in various sources as Kaiser, Kayser, Kuyser and Kyser — in February 1817 in North Carolina, and married Joseph Hess in Van Buren County, Arkansas, when she was just 18 years old. 1 Her first four children were born in Arkansas, the fifth in Missouri, and the last eight in Oregon — for a total of 13.2

Mary Louisa, often called Louisa, and her family were among the pioneers of the Oregon Territory. They’d been there long enough by 1850 to have had three children born there.3 The county where they settled, Yamhill County, was primarily farm country,4 though Joseph was shown on the census as a merchant.

And they’re recorded there in 1860 with their youngest 11 children, ages four months through 20 years; Joseph was shown as a farmer with substantial property.5

But by 1870 Joseph was a no-show on the census. Mary Louisa, age 52, was recorded as head of household with five children ages 11-19.6 And before the 1880 census, Joseph was dead.

The story was that Joseph took off for California, ended up back in Oregon with another wife and other children, and died — by murder or by accident — from a blow with an axe.7 The full story of the split between Joseph and Mary Louisa isn’t shown by the records I was poking around in. The story that is shown is of a woman who began to live — and control — her own life and affairs.

The first deed recorded in Yamhill County in Mary Louisa’s name alone was for 20 acres in 1878 to two men, W.A. Roberts and W.H. Deemer.8 She continued to transact land business throughout the 1880s and 1890s, selling or even buying land.9 As late as 17 December 1902 — only weeks before her death on 20 February 190310 — she transferred two acres to her son Tilman.11

So what must it have been like for this proud and independent woman when, in March of 1901, all of a sudden, she had to prove she was competent to transact business? That she knew what she was doing? What in the world could have prompted the requirement that, count them, four separate affidavits — including two from medical doctors — had to be filed before a deed was recorded?

Because that’s the tale that’s told by two pages in a volume that FamilySearch labels as miscellaneous records. On the 12th of March 1901, two long-time acquaintances of Mary Louisa’s traipsed into the county courthouse and filed affidavits. The first one, J. C. Nelson, swore:

I have personally known Mary L. Hess for the past fifty years, and … she is now and always has been so far as I know, possessed of her right mind. I consider her perfectly competent to transact business. I talked to her this day concerning the sale of that certain tract of land, made this day to W.R. Carter and I believe she sells it thoroughly understanding the purpose for which it was sold. I further say that I verily believe that she has not been coerced in any way whatsoever in making this sale.12

The second one, L.W. Harger, said the same thing, except he’d only known her 26 years, not 50.13

Then came the doctors, Horace J. and Harrie A. Littlefield, and in identical language each said:

I am a duly licensed and practicing Physician, and … I have this day made an examination of Mary L. Hess and I find that she is in full possession of all her mental faculties, and in my opinion she is well qualified to attend to the transaction of any business to which she might have to attend.14

The affidavits don’t tell us why they had to be filed — what caused somebody somewhere to ask about Mary Louisa’s competence. It surely wasn’t the land deal itself. She was selling a little more than 93 acres of land to W. R. Carter for about $30 an acre15 and other large land deals around the same time were for less per acre.16

Perhaps she’d been ill. Perhaps one of her 13 children was worried about his or her inheritance. Perhaps she’d just been a silly old woman — she was, after all, 84 years old at the time — and worn purple with a red hat.

We don’t know. We don’t even know how she reacted to this indignity. I’d have been furious. Maybe she was too. Or maybe she understood, for reasons lost to time.

All we know for sure is that these two pages of an obscure record book tell a story about Mary Louisa that would be easy to miss — but that ought by rights to be part of her history.

Because she was, by golly, “possessed of her right mind (and) perfectly competent to transact business.”

Which is more than can be said for a lot of us…
