Impact of Mysorean invasion on Tulunad

Did the region see any significant changes during this period? Are there any accounts from local sources? I have read that Hyder Ali was pragmatic, so did try to maintain status quo in his domains. But Tipu was a despot and is said to have renamed Mangalore as Jalalabad. Multiple sources speak of captivity of Catholics at Srirangapatna. The scale of the difficulties and the number of captives could be biased. Any reliables sources to back these claims? (Anecdote) One custom followed by many Catholic families in the past was naming a dog tipu if it was born black. But just like relevance of caste among Catholics, even this could be dying out!
