Ellen Seymour Loomis

My GGGrandfather was Daniel Dutin Hanson, he married Cornelia Barbard Seymour. They had a daughter, Ellen Seymour Hanson, who was born in Hartford, CT. She married Archibald G Loomis. I'm looking for both the ancestry of Daniel Dustin, and the descendency from Archibald Loomis. I've also come into possession of some Loomis pictures of Madeline S Loomis and her father, and of an unnamed woman, could be Cornelia, taken in Harford. I would be glad to scan and send copies to anyone helping with this line. Thanks in advance.
