I am looking for information on the name Roullier, from what I was told Twin River(s), Canada, and later settled in NY, with ties to the Seneca tribe. From what I was told the Roullier name ties my genealogy back to Seneca. However, I don't have a name. The only name I have is Singuor Roullier, who would have came later, at least in my tree. Thanks for your help.

What time period are we talking about for Singuor Roullier? Birth? Death? Census? Male, female?

You would have to trace Singuor Roullier to parents and backward to see IF there is any connection to any Senecas with the same surname. There may not be.

I am positive that we have Seneca in our family history. When my great, great uncle died the family history book/ bible where he kept the information was lost. However, all my family members remember seeing the name that was linked to the Seneca, which we know came from the name Roullier.
Singuor was born in French Canada, and migrated to the U.S. in 1836, he was born in around 1824. That out of two weeks of looking on ancestry is all I can find at this moment, but I am still looking. I just want to know where my family came from, although I have found more out now, since the bible was lost in 1989.

You still need to trace the family line first in order to accomplish your goal.

First, I recommend you join the Roullier surname mailing list at Rootsweb and post there. Also post your message to the Roullier message board since not all Roullier researchers may belong to the list.

I would check immigration records from Canada for the time period )ca 1836) looking for someone about 12 years old. The spelling of the first name that you are using does not show up anywhere on the Internet, so be open-minded regarding the spelling of the first name, and the surname, too, for that matter.

You said he came to the U.S., but did not say where. You
need to check records in that area as well as Canadian records.

If you have not yet traced your family line back to Mr. Roullier, you need to do that, and trace the collateral lines as well. It could be that another decendent has information to share; but you need to know the lines that married into the family in order to connect with them.

Learn enough French to be able to translate the the words born, died, married, baptised, witness, etc. so when you come across the records you will be able to understand them.

You also need to check Roman Catholic records in Canada. They were extremely good at keeping birth and baptismal records clear back into the early 1600s.

Good luck!
