James K. Polk Strayer is my great grandfather. I have gathered a lot of information about him, his wife Martha Washington (Belding) Strayer, and their 14 children. I recently added headstone information in Find-A-Grave in the Mahaska Cemetery, Mahaska, Kansas, which is where James K, wife Martha, and children Mary Elizabeth (Strayer) Thaller, Nellie, Gladys, Martha "Mattie", Halbert Ernest Strayer, Jr., William and Rhele "Rita" Strayer are buried. Lettie Jane Strayer (1st wife of James Hubert) is also buried there, along with Glenn Virgil (son of Mary Elizabeth) and his wife, Velda.
If you are interested in following James' daughter, Emily Catherine, she is my grandmother and she and her husband, KI Turner, and her son, Berl I, are buried in Broughton Cemetery Broughton KS. I have them up on Find-a-Grave also.
If you want to exchange more information, just email me.
