Yes, Payer's Patches are usually found in the lower intenstine.
Peyers Patches
peyer's patches are found in the lowest portion of small intestine.
The jejunum is 2m long while the ileum is 3m long. The jejunum is thicker and more vasculaure than the ileum. There tends to be more plicae circulares in the jejunum region. As for the ileum, the peyer's patches are more common in this region.

Distinguishing feature of the duodenum are the Brunner's glands, whereas the Peyer's patches make the ileum easily identificable. The common bile duct and the pancreatic duct enter the duodenum, whereas the ileum does not receive duct from other organs. Outermost layer of the duodenum is comprised of adventitia as it is located retroperitoneally, while the outermost layer of the ileum is represented by serosa(mesothelial cell are evident). The ileum has also more goblet cells than the duodenum. Duodenum represents major site of iron absorption, while the ileum-B12 absorption.
Peyer's patches (or aggregated lymphoid nodules) are organized lymphoid nodules, named after the 17th-century Swiss anatomistJohann Conrad Peyer. They are aggregations of lymphoid tissue that are usually found in the lowest portion of the small intestine ileum in humans; as such, they differentiate the ileum from the duodenum and jejunum.
They're much more numerous in the duodenum than in the ileum.
