There is nothing like Pithru dosha in these days. It is just a combination of Rahu and Sun in a horoscope which happens even for those having no observable pithru dosha. In Kaliyuga in particular, there is no pithru dosha at all since howmany children are born to a man is unaccountable with one legally wedded wife and many concubines kept in secret. You forget about it and if at all you feel that you should do something to remove it read SriKrishnakarnamurutham 108 times which will be possible in about a year if you can read one chapter a day.
