I have made a hobby of “collecting” Fairweathers. When I first became interested in family history, I found that there was little on the web which included Fairweathers worldwide. So, I decided to start a database which I posted on Rootsweb’s World Connect, the free website for genealogists.
    I post the basics of my information there but not my sources & notes. I want to encourage people to contact me so that we can exchange information. My database contains more than 62,000 entries & I regularly add more people & data. Some entries are just bits of information that I have found. Links between people range from those with official proof to ones where I have made an educated guess. I feel comfortable doing this as it fits with the goal of my database but I encourage people from that tree to ask me for sources & to obtain official documentation if I can’t provide it. I am happy to correct mistakes.   
    I am now registered with the Guild Of One-Name Studies. I am happy to announce that a Fairweather DNA study has been formed.
You can access it at this website: Family Tree DNA. I encourage anyone who is interested to get in touch with me about that. If you have found information that was helpful to you through my  database, I ask you to consider donating to the fund on the DNA page. This would be used to help new participants cover part of the test costs.
    Please visit the other pages on this website; there are pages for Photos, Notes, Links and Credits which can be clicked on at the top of each page. You can email me by clicking on the link at the bottom of each page. I’m still having some email problems with the links here but you can track me down through other links.
    I don’t publish anything at all about people born less than 100 years ago but may share it privately with others from that same family tree. If you have ever written to me & not had a reply, please contact me again. Real life sometimes sneaks up on me & distracts me from the fun of this study! :-)

My own Fairweathers  came from Scotland to New Zealand on the Lady Nugent, leaving Gravesend in England in October 1840 & arriving in Petone on March 17, 1841. They were Wesleyan Methodists who settled in Wainuiomata. Within 10 years, both parents had died and their seven children moved to many areas of the North & South Islands.
