Lord Shiva was imparting wisdom to Goddess Parvathy. Parvathy was distracted by a beautiful peacock and lost her concentration to the subject detailed by Lord Shiva. Lord Shiva cursed Parvathy that she would take birth as a peacock. She visited several places and finally reached Mylapore. Here she performed penance and Shiva Pooja under Punnai Maram/Tree. Hence this place is known as 'Mayilapur' which is colloquially known as Mylapore today (Mayil in Tamil means peacock and Mylapore refers to an Abode of Peacocks).
Lord Shiva was pleased with Parvathy's penance and the celestial wedding ceremony of Shiva and Parvathy took place in Uthiram Nakshatra/Star in Panguni tamil month. Every year Brahmotsavam is held in the month of Panguni and kalyana utsavam is held on Uthiram Nakshatra star day.

Punnai Maram-Sthala Vriksham under which Karpagambal performed Penance
There is saying in Tamil that 'Kailaye Mayilai, Mayilaye Kailai'. It means that Kailash in Sanskrit or Kayilai in Tamil, the celestial abode of Lord Shiva is the same as Mylapore and Mylapore is the same as Kailash to Lord Shiva.
Agasthiar.org details that Mylapore is Kailash itself owing to the 7 Shiva Temples in Mylapore in their website link below,
The Seven Shiva Temples in and around Mylapore are as follows,
6) Malleswarar7) Kapaleeswarar
Brahma Deva was proud that he had five faces and Lord Shiva wanted to teach him a lesson. Lord Shiva plucked the Fifth Head of Lord Brahma. The Fifth head stuck to Lord Shiva's hand as Skull which is known as Kapalam in Sanskrit/Tamil. Hence Lord Shiva here is known as Kapaleeswarar.
Karpagambal: Karpaga Vriksham
Agasthiar.org details that there is an invisible Karpaga Vriksham in front of Karpagambal Devi and Vayilar Nayanar in the Temple. Karpaga Vriksham in Tamil or Kalpataru/Kalpa Vriksham in Sanskrit refers to the divine wish yielding tree in heaven which grants all wishes of people under its shade. Karpagambal also grants all the wishes of her devotees who approach her.
Kola Vizhi Amman-Kaval Deivam of Mylapore
