layman opinion: no it's not, your brain is a graph compressor.
I had episodes of minute memory losses in the last years. And everytime I gathered the answer after long time by having flashes of things similar in nature. Trying to remember a name, I went through a stream of wrong names of people of the same origin, and same prefix (bou) until the right suffix hit me.
When I think of my current partners name, I sometimes cycle chronologically through all past partners until I get to hers. Normally in my mind, but sometimes out loud.
That should be a fairly deep rooted memory. If you're having difficulty recalling, that is concerning. I respectfully urge you to consult with a neurologist or at least your GP.
I'm still pretty young and have had a somewhat robust love life. I sometimes wonder if I am not just audiating the brains internal lookup of the information anyway. If I am focusing then name recal is normal thankfully!
