i think that the practice emnated from the chittappas and athais (who were
about 15 years + when the kids were born) calling father as anna and that
stuck. or perhaps the mother addressing father as "enNa" also contributed.
i have a peculiar situation in our family where my great grandfather was
addressed by his children as Anna whereas my grandfather was called "appa"
by his own brothers and sister.
