Is there any chance that the 420 sq ft cabin was rented out?
I have no idea, I wonder if the two daughters used the “cabin” as their very own “playhouse”. It is curious that Orland and Thelma’s oldest daughter would have been six in 1961 and would remember if a woman and baby were living in the little cabin in the backyard and yet nothing can be found about her. I also have not received any word from UH regarding when Orland returned to teaching at UH. I received word from UW at Madison less than 12 hours after I sent my query which was sent the same day I sent my query to UH, now more than a week later.
Even the memorial at UH for Professor Orland Lefforge is extremely sparse numbering perhaps 6 lines while memorials for other deceased faculty are multiple paragraphs.
Finally, the house is located over 7 miles from the closest hospital (Kapiolani) which would be an odd choice for a pregnant woman faced with a drive to give birth. Even the home for unwed mothers on Oahu was located less than a mile from the hospital.
There would be IRS records of income for rental property, if the ‘cabin’ (it was an out building, perhaps a 21 x 20 structure, more likely a storage building) were rented out.
