Hi, Julie,
I don't see a connection, although Sarah's father, John George Sr. was born apparently born in "Lockley," Staffordshire and later lived in Toxteth Park area on Wellington Rd. Another of my surnames from that area was Thompson.
It appears that your Sarah Jane Ford married Seth Holden in March of 1867 in Wolverhampton, Staffordshire, per the free free Rootsweb B/M/D website (a work in progress). Perhaps you already knew this. If you haven't already, you can send away for a certificate, apparently, using the reference number Vol. 6b, pg. 681.
I was surprised to see that they had other data regarding "Seth Holden" individuals. I would have thought it might have been an unusual name. Perhaps some of that data is related to your Seth.
