How to merge two datasets that have different column names in R?

I have 2 datasets

x_data has 130 variables (columns)

y_data has 126 variables (columns)

Both data sets have information I need but after doing

intersect(names(x_data), names(y_data))

Only 19 columns actually match.

For example, x_data has the column "Frist Name" while the column also exists in y_data but as "FirstName".

There are multiple examples of this but there also may be columns that exists in 1 dataframe but not the other.

If there a fast way for me go edit these columns so they can have the same name?

My end goal is to rbind() to merge these datasets vertically.
