I have recently commenced researching my families history on my grandfathers side and have found a Maddern connection.
My grandfather was George Albert Wellington the son of Abraham Wellington & Elizabeth Stuart. His Grandparents were Richard Wellington & Caroline Matthews & his Great Grandparents were Peter Wellington & Joan Harvey.
I am connected to the Madderns through Walter Wellington (son of Peter & Joan)& his 1st wife Phillipa (maiden name unknown at this stage). Walter & Phillipa's 1st child Phillipa married a Richard Maddern in July 1856.
If there is a connection there with you, I would be very happy to hear from you.
