I dont5tbink its as old lady as others do.
That'll be because you are a lot younger than me. 
It's a generational thing - the names that have been fashionable over the last 6 years or so, are names of my great Aunts and Uncles, Grandparents etc. People having babies now will be much younger than me, so won't have pictures in their minds of all the 'old ladies' these names remind me of.
I suspect some younger folk think that Margaret, Alan, Elizabeth, etc. are 'old people's names', then in 10 - 15 years folk will say the same about Susan, Debbie, Karen, etc.,,,, and so it will go on
