My Seabrook ancestors were living in Bethnal Green/Hackney in the mid1800's but I've found that my gt-gt-grandfather was born in Bedmont or Bedmond or Abbot's Langley (Varies between censuses). It looks as if he had brothers , Frederick b.abt 1820 and George b. abt. 1812 - both Abbot's Langley. My ancestor Thomas Seabrook married Sarah. Frederick married to Emily and George married to Elizabeth.
George and family lived in Herts all the time. Frederick was in Bethnal green 1850's-60's, back in Herts 1871. My Thomas it appears, stayed in Middlesex. Any information or possible connections welcome. Ann
