Of course, this also bolsters the credibility of the newspaper birth announcement. There is nothing hinky about the address, given it belonged to the young student mother's parents.
And it is also understandable that the neighbor has no recollection of a mixed-race child, given Stanley Ann would have been there at most a few days, before decamping back to Seattle, leaving the father of record behind to finish his studies at the U of H and the possible father in fact to continue bar hopping with his comrade Stanley Armour Dunham.
I doubt there was a livable cottage on the property in 1960-1961, apparently the records showed an outbuilding without a ceiling when a freeper contacted the local authority and reported back on one of the long threads, (don’t ask me to find it again) I am going by memory. There was no record of a cottage.
I notice there’s either an ‘r’ or an ‘h’ in front of every residential street number. All those properties could NOT have had a rear dwelling. The letters must stand for something like ‘resident’ or ‘householder’ as has been explained me once or twice. ‘Householder’ standing for the HEAD of the household, and resident for everyone else living there.
The biographer offers that the Dunhams shared the house with the family Stanley Armour was working for, he maintains he spoke to their daughter. The name PRATT is the same as his listed employer. Anyone able to look through a Polk for that period would probably find PRATT listed at that address, by looking under ‘P’ - correct?
