Is there anyone out there that has a subscription and can look up stuff for me?

I have tried to find my families but because I do not have a subscription to any of the websites I have hit a brick wall. I need help finding the SNOW family that originally came from Ireland and settled in Scotland. I think they were from around Lanark. Also I am looking for the HAMILTON family that were from Scotland and went to Ireland. Also the HAMILTON family that left Scotland and went to Canada. If there is anyone out there that can help me I would be very grateful. Send any replies right to my email address.
