In the above link it is given that the stotra is from Ganesha purana but it's not. There is a hint in the below document at page 21 that the stotra might be from Skanda purana

If anyone happens to know where exactly in Skanda purana the stotra is mentioned, kindly let me know.

Answer 1

This stotra is from Mudgal Puran and known as Ganesh Dwadashanaama Stotra. However the last 4 names are not mentioned and there are some minor changes such as 'Bhaalchandro' instead of 'Phalachandro' etc.

The last name Skanda poorvaja also does not tally with a Kartikeya Stotra '.... sharajanmaa gaNadhIshapUrvajo....'
