If the father is nearby u could arrange to do the naming in presence of a Pastor .Find a godly pastor they'll be of assistance.Most Churches may not want to do it if the child was born out of wedlock. Similar scenario happened in my church though my pastor initially refused to conduct it,later he sent me to go and conduct it

A journalist impregnated a lady he intended marrying while still courting.when it was time to name the baby,the father insisted on conducting it.The guys family objected saying it was aginst the Yoruba tradition to do so and the lady's father told them if they dare take the baby away for it the child will not come back alive.eventually the man's family got a pastor to do the naming in the lady's father's house.Some days later the father did his own in the Islamic way and they even shaved the little baby's hair.This has caused a serious problem nowThis is areal life problem someone asked me for counsel and I want people to pls help me.
