William Moreton, Esq - The Moreton and de Lancaster of Raynhill families

https://en.wikipedia.org/wiki/Little_Moreton_Hall#House

As supporters of the Royalist cause, the Moreton's found themselves isolated in a community of Parliamentarians.[20] Little Moreton Hall was requisitioned by the Parliamentarians in 1643 and used to billet Parliamentary soldiers. The family successfully petitioned for its restitution,[21] and survived the Civil War with their ownership of Little Moreton Hall intact, but financially they were crippled.[20] They tried to sell the entire estate, but could only dispose of several parcels of land. William Moreton died in 1654 leaving debts of £3,000–£4,000 (equivalent to about £12–16 million as of 2010[22][e]), which forced his heirs to remortgage what remained of the estate.[23] The family's fortunes never fully recovered, and by the late 1670s, they no longer lived in Little Moreton Hall, renting it out instead to a series of tenant farmers.

His wife Jane's father Thomas de Lancaster of Rainhill I and her brother John both Royalist Estate was lost as well, but they didn't recover the Estate at Raynhill and John was convicted and executed.

Perhaps, it was just the link between the two families. May try to find documentation.
