Both good options, but I prefer [name_m]Lowen[/name_m]. [name_m]Grayson[/name_m] was very popular 10-15 years ago, and I never cared for it. “Gray” gives it a gloomy feel imo. [name_m]Lowen[/name_m] is gentle, unexpected, and yet familiar due to its similarity to [name_m]Owen[/name_m] and [name_m]Logan[/name_m]. Both sound great with the middle name [name_f]Parks[/name_f]! Best of luck to you
