Obsolete (livinty)

I used to make use of the word livinty years back to indicate the noun of real or live. But I have never heard been used by folks before, but my father made use of it.

Is it that obsolete?

I cannot find any evidence that there is, or ever was, an English word “livinty”.

The most obvious nouns of “real” and “live” are “reality” and “life”.
