MrsRickP on Family Tree Circles

Hi, Tracy here, a newbie. I am embarking on researching my Dad family history. Alas I really never too notice of him and history in my younger days. Now that he has passed, over 20 years now it is time for me to start!
Can I give you some basic info so maybe someone can offer some advice or posts about him.
His name is David Rupert DENSEM..born 10 May 1928 or 29. Born in Christchurch NZ. That's about it for now. Many thanks for any help I may receive.
Regards
Tracy
