Solemn, dignified, or sunlight
Souline is a rare name likely derived from the French 'solennelle', meaning solemn or dignified. It may also be interpreted as a creative blend of 'Soul' and the suffix '-ine', or a variant of Soline, which relates to the Latin 'sollemnis' or the Spanish 'sol' meaning sun.
