Lewis Whakapapa

Tracing my whakapapa has been a hard the more I think I found not even.
Now what I have found on these two people are hear say, Maata Te tuku Te Waharoa one way of spelling last name, the other way Whararoa????? I think she was born in Otorohanga Waikato as I had only found out theres family land again hear say. Next person Tawi Lewis wife Tapapa Tahuri Tinimene I think this is how it is spelled.Getting the right spelling is not easy. If anyone can help with the spelling or help in anyway please contact me, I do have some info to compare with.
Cheers
Keita
