Yorkshire holds the honour of being the most Taskered county in England, with over 2,600 IGI records – over twice the number of second place Lancashire.

There are just two records before 1550, Isabell Tasker, born in 1542 at Bingley and Dorothy Tasker, born about 1549 in Rothwell, who married John Smith there on 16 January 1571. However between 1550 and 1600 there were lots of Taskers – mainly in the West Riding but with a few in both North and East Ridings.

Halifax was home to a thriving early family, starting with Johis Taskar's sons Edward (christened on 9 July 1553) and Anthoni (3 March 1555). Edward then married Sebbell Deane on 10 Jun 1583, with children Johne (1584), Anthoni (1586), Samuel (1589) and Johnas (1592). Meanwhile Anthony (now with a 'y') married Sebbell Croyser on 11 May 1578, with children Marye (1579), Susan (1581) and Johne (1584). Some 10 miles north, at Keighley, Richard Tasker married Jennett Brand on 20 September 1559 then 40 years later Ralph Tasker married Jennett Sympsonne, on 26 November 1599. And 10 miles east of Keighley the small village of Calverley was home to William Tasker's sons William (1597) and John (1602).

About 25 miles east of Halifax, just north of the town of Sherburn in Elmet, is the little village of Saxton, then known as Saxton in Elmet. It was there that the largest tribe of early Taskers developed, starting with two presumed brothers: Richard and Edmond. Richard Tasker's children included Thomas (1561), William (1565), and Ralfe (1569). A further three children - Jonye (1592), Mathew (1595) and Frances(1598) probably belonged to another Richard, or another wife. Edmond Tasker was having children at the same time as Richard: Isabell (1568), William (1570), Edward (1573), John (1575) and Ellin (1579). Then Thomas Tasker christened Anne on 24 Aug 1588 and Ralphe on 8 December 1592, and Elizabeth Tasker married Francis Taylor 15 November 1595 (or this may have been at Keighley). In addition to all these, there are 3 other children listed for Saxton with no parents: Richard, christened in 1563, Thomas in 1581 and Margaret in 1584. This extended Tasker family then developed even more throughout the 1600s.

The early East Riding Taskers were located just north of the Ouse/Humber in three separate villages. Isabell Tasker married William Allison on 13 July 1562 at Holme Upon Spalding Moor, then there were two Tasker weddings at South Cave: Richard Tasker married Katherine Hunsworth on 27 November 1576, and Jane Tasker married Robert Hooton on 19 May 1593. The only birth was that of Richard Tasker's daughter Margaret, christened at Howden on 8 June 1588.

The village of Nunnington, midway between Malton and Helmsley has the sole Tasker record in North Yorkshire before 1600, and then only by a few days, as Thomas Tasker's daughter Helena was christened on Christmas Eve, 1599.
