I am about to enter the 11 children of John Kilduff and Sarah (Buckridge) Kilduff into WikiTree. But the only source I have is "My Heritage"where I am a member. I do not have birth, marriage or death certificate numbers and would like to know if this organisation is a suitable source. I have also used " Hawkesbury Pioneer Register, Vol 1 & 2 before on his profile, but apparently this record is not acceptable. Please help.
