A number of knitting patterns were issued under the Ursula duBois name between 1964 and 1969. Interestingly enough, these patterns were 15 - 75 cents higher in price than the norm for this time period. Frequently, the pictures were low quality, making it difficult to see the merits of the garments. Many of them, however, were modeled by actresses; in this case, Pat Woodell. To a smaller extent, the patterns were syndicated across various newspapers. I've found evidence of 5.
There is two hints out there that Ursula duBois may have been an actual person, not a syndication name. The first hint is that her name was updated to Ursula deBois Lewis in mid 1968, implying a marriage. The second is business license was obtained under the name (whereas we do not see this with syndicated names).
In the meantime, I copied off all the patterns/columns I found and my putting them out here and there in my daily stream over at Facebook. They are set up in their own Album - Ursula duBois, should you like to take a look.
Thanks for dropping by,
