I can see some of the currently dated girls names with nice sounds could start to come back by 2030 - Sylvia, Patricia, Sandra, Linda, Angela etc.
I also think classics like Jane, Anne, Helen, Ruth, Susan, Frances, Mary and Margaret will eventually come back, as fashion starts to move back away from the more cute/sweet or frilly/princessy sounding girls names.
And the more classic of the boys names popular years ago - John, Robert, Simon, Peter, Phillip, Paul, Stephen, Richard, Hugh, Nicholas etc should be moving higher up the charts by 2030.
