In an attempt to find Aquilla I looked for Justina's husband John Eaton to see if he had a relative who could have have Aquilla. John Eaton and wife of York Borough in the 1800 census are John and Justina. By 1814 she is in the tax records as Justina Eithin with a house and a lot in Shrewsbury. in 1815 she is Eadon. Other records have Eton, Eaten, Iten and Itten. She was not there in 1813.
I need to check Cordorus Twp taxes as her daughter Catherine was christened there at Lischy's Church now in North Codorus. There are 3 records in the deed books I need to check that occured after Justina's death 11/28/1869. Her tombstone says she was 93-10-3 which gives her age as a little older than the 1850 census would indicate.
