For the most likely birth decades for those marrying now, Nicholas was the 19th most popular baby name for boys in the 80s, and Rachel was the 16th most popular for girls. In the 90s, Nicholas jumped to 6th, while Rachel inched upward to 15th. That’s a lot of Nicks and Rachels out there, so the likelihood of a Nick/Rachel marriage is quite high. BTW, this data comes from the Social Secuirty Administration (bit.ly/SSANamesData) and it’s fun to play with.
