What does Alice mean?
Alice comes from the Old French Aalis, a short form of Adelais (Adelaide), from Germanic elements meaning “noble.” Lewis Carroll’s Alice in Wonderland fixed it in the imagination.
What does Gertrude mean?
From Germanic 'ger' (spear) and 'thrud' (strength), so 'strong spear'. The 'spear' element is a weapon of war rather than 'warrior' outright, but the martial sense is well established.
