@FeeFee832 You are getting a lot of jip on this thread really unnecessarily. Most people choose normal names, that’s why they’re normal! You asked for classic options not a slating for liking classic names!
Grace or Elizabeth Grace are both great. Also maybe Anna (think this means grace), Mary, Eliza (could be a nickname for Elizabeth), Nina, Lucy, Holly, Rose, Alexandra, Alice, Charlotte, Jane?
For boys, William and George are both great. Other options Charles, John, Andrew, Thomas, Samuel, Benjamin?
Good luck
