Aebbe is from the Old English ebbe (low tide). Saint Aebbe of Coldingham (d. 683) was the Northumbrian princess, sister of Saints Oswald and Oswiu, kings of Northumbria — abbess of the great double monastery at Coldingham on the Berwickshire coast.
The headland she ruled is now called St Abbs Head.
Aebbe does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Aebbe reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
