Given her parents marriage in 1603, and her siblings births in 1606, 1608 and 1611, Jane was either born in 1604, and aged 23 at marriage, or about 1609 and about 17. Most of her siblings were over 20 at marriage, so the former is more likely. There is no difinitive marriage record, however, their daughter Elizabeth was married in 1645. If she were only 17, she still would have been born in 1628. Since Jane and Experience were not yet married at the 22 May 1627 Division of Land, yet Experience was included in the Cooke family’s division, they likely married soon after.
Estimated death in 1640 due to husband's second marriage. Mary, b. abt. 1632, (based on her marriage in 1652, though perhaps as late as 1634), is thought to be Jane's last child because there is a large gap until the next child Sarah b. abt. 1641. But there is no proof Mary belongs to Jane. Thomas is only child proven to be Jane's (by her father's will), and Jane is accepted as Jane's because she is thought to be the oldest child, i.e., older than Thomas, and so having the same mother.
