Looking for Info on Annie Margaret Cheyne Woodville New Zealand

There are 2 Cheynes buried in the Old Gorge Cemetery in Woodville

Ann Margaret Cheyne is the only one I have a very little info on
- she was born about 1878 and died 11th May 1947 aged 70.
She is buried in PLOT 3, BLOCK 20

The other is Christine D. Cheyne - born about 1847, died 23rd September 1934 aged 87, buried in PLOT 4, BLOCK 18

Any information on these 2 women (possibly mother and daughter) would be greatly appreciated - especially who were the men in their lives and what they were doing in Woodville
