Patterson Family Creevyloughgare

I live in New Zealand.  My ancestors were William (c1810), Andrew his son (married Rachel Purdy 1853), and John (Andrew’s son born about 1860).  He married Lizzie (Eliza, Elizabeth) Boyd in 1880.  She died about 1882.  One child Eliza Jane born 1881.  John was a Tailor in Ballynahinch.  He emigrated to NZ 1887.  H Cecil Patterson was a cousin to John.  Does anyone have any information about this family?

Thanks.
Sally Billington (nee Patterson)
