I'm a bit late to the party on this thread but I thought I might add some information. The John Perry that is shown in the 1851 Census in Kates Hill, in 1861 on Price Street, and in 1871 on Price Street with wife Elizabeth and children Charles (b 1845), Sarah Ann (b 1843), Susannah (b 1851), John S. (b 1854) an Elizabeth (b 1860) consistently provides his birth year as 1818. This potentially corresponds to a baptism record for a John Perry born to Charles and Susannah Perry, both of which are repeated in the names of his children. The John Perry born to Timothy and Sarah was baptized in 1822.
I think a John Perry shown with wife Mary Ann and children Catherine and William in 1851 in Tipton, birth year about 1821, might be the correct John Perry to be brother to William. There is a burial record for a Mary Ann Perry in 1852 and then an 1859 marriage record for a John Perry, widow, with father listed as Timothy Perry. This John Perry left Staffordshire between 1861 and 1871 and settled in Wales. Then in about 1879 or 1880 he left for the States with his stepdaughter (on paper she should be a step, but I think otherwise) and died in Pennsylvania in 1893. This John Perry's year of birth is consistently shown as 1821 or 1822 in censuses, except for the last in 1880. In the interest of full disclosure regarding my theory there is a problem with the record for this John's first marriage to Mary Ann: the "best" record I have found lists the groom's father as Thomas. But in all my searches I have not come across ANY marriage record in the right time frame for a John Perry to Mary Ann with the groom's father Timothy. There is no doubt, however, that the widow John who remarried in 1959 with father Timothy was married to a Mary Ann first based on the baptisms of the children and then the family group in the 1861 Census.
I've only just begun researching the brothers of John, who is in my direct line, but it looks like Zarah and his wife also went to Pennsylvania and died there. In the 1880 US Census there are Zarah and Honor Perry, both born in England, in Pittsburgh, Allegheny County, Pennsylvania with sons David and Joseph. Further, there are find-a-grave.com memorials to both Zarah and Honor. This for Honor: "Birth 1826 Worcestershire, England Death Mar. 26, 1898 Pittsburgh Allegheny County Pennsylvania, USA, Mrs. Honor Perry, aged 70 years, died Saturday at her home in Avonmore. She was the widow of Zara Perry. The funeral services will be held from the residence of her son, David Perry, Etna, tomorrow. Pittsburgh Press - March 28, 1898" And this for Zarah: "Birth 1827, England Death Dec. 10, 1890 Pittsburgh Allegheny County Pennsylvania, USA On Wednesday, December 10, 1890, at 1:15 p.m., Z. Perry, aged 72 years 1 month and 5 days. Funeral from his late residence, Thirty-ninth street, Pittsburgh, on Friday, December 12, at 2 P.M. Friends of the family are respectfully invited to attend. (Alton, Ill) papers please copy".
The will shown in this thread for Zera Perry might apply to one of Timothy Jr.'s sons-Zechariah. There is an 1872 West Bromwich marriage record for Zera Perry with groom's father Timothy, and a 1919 Dudley death record for Zerah Perry age 70, birth year about 1849 which would correspond to Zechariah shown with Timothy and Priscilla Perry in 1861 and 1871.
Also, someone else added early on in this thread that there were sisters in this family but I'm not so sure. There was another Timothy and Sarah Perry having children in Staffordshire (Wednesfield) at about the same time and earlier that had daughters and a son named Timothy I think too.
Any thoughts?
