Lots of other DB's (e.g. <MillBase>) conflate his games with another player:

<Janes, Miroslav> who was active in the 1990's.

The other Janes might be from Nova Scotia area (or somewhere in Canada):

which might match this guy:

except for the middle name.

But it looks like he was a Banker from Leroy, according to 1955 paper:

<Here Kenneth R. Smith of Dallas won the Southwestern Open Chess Tournament in the Roosevelt Hotel Sunday and in third place was a 17-year-old boy, Juris Jurevics of Dallas. Second place winner was Allen II. Baker of San Antonio who was also named secretary ol the Texas Chess Association which sponsors the yearly tournament. Fourth place was won by William H. Janes, Leroy banker who won fourth place last year and fifth place was taken by Blake W. See CHESS, Page 2 >

OK, that's enough to find him, I think:

<William was born on July 10, 1916 and passed away on Friday, July 23, 1999.

William was a resident of Leroy, Texas.>

William H. Janes appears to be certain, so if you're certain of that player's dates they can be added.

His bank went belly-up in 1987, very soon after Janes sold the private bank to a new owner.

<

Tall, thin, and reserved, Bill Janes assumed control [of the Leroy Bank, from his father] at the age of 37 without a hitch. With degrees from Baylor and Columbia universities, he was better educated and more cosmopolitan than either his father or his grandfather. Janes, like his father, taught Sunday school at the Leroy Church. His lessons were laced with erudition — he would bring a book or a magazine article to elaborate on a biblical theme. He played chess skillfully, wrote poetry, and brought a touch of class to the country bank.

In an odd way, Janes was a part of Leroy yet apart from it. His professional and personal lives were intertwined with the fortunes of his hometown. But perhaps his education, his financial expertise, and his trips to Europe, helped distance him and his wife, Jessie Lee, from the other Leroy residents. In a town defined by close relationships, few could say they knew Bill Janes well.

In 1974, with Waco encroaching on Leroy, Janes led the town to incorporation and became its first mayor. He had a hand in nearly everything. Under his twelve-year leadership, Leroy got its first street-lights and street signs. Janes also researched the town’s past and published a pamphlet on the history of Leroy.

With such a man in charge, it’s not hard to understand why people of Leroy entrusted their money to the bank he owned, insurance or no insurance.

On May 26, 1989, the Texas Attorney General’s Office filed its own civil charges of fraud, negligence, and deceptive trade practices against Bill and Jessie Lee Janes, Bill Tankersley, and Ronald Bailey [Tankersley and Bailey were involved in taking over the bank - it's not clear who actually bought it]. There is a critical difference between the state’s and the depositors’ cases: The state is representing all of the depositors in the bank, not just the 376 plaintiffs in the earlier lawsuit.

There is a great deal of confusion about what went wrong at the bank. Still unknown is how much withdrawals by skittish depositors contributed to its insolvency. Banking officials say that they also don’t know whether Bailey or Tankersley legally owned the bank at the time it closed. And they don’t know precisely how much Bailey and Tankersley contributed to the bank’s downfall or how much may have been beyond their control.

One thing is certain: The bank’s troubles began long before it was sold in the spring of 1987. “That kind of damage doesn’t happen in a couple of months.” Says banking department attorney Carlos J. Contreras III. Commissioner Littlefield says, “I can understand why people thought a lot of Janes, but as a banker, your first responsibility is to protect the interests of the depositors. You’re not loaning your own money. You’re loaning theirs.”

Janes has insisted in depositions that the bank was sound when he sold it. He says he did not seek out a buyer; Bailey and Tankersley approached him out of the blue in the spring of 1987 with an offer.
