And here I was so anxious in thinking you might really find the gravesite

Well, first not sure if maybe part of not finding the grave plot is that the last name should be "TAYLOR" not Turner. They are William Thomas and Mary Ann (or Marianne) Taylor.
I wrote my Aunt another letter yesterday and asked if I could have a copy of the records she has to look at them myself.
Second, yes, even though I didn't write back about it.....I do realize Birkenhead and Seacombe are two different places

I would be interested in looking at the site map. My aunt answers very quickly so maybe in a week or so I will have the copies of the records.
Thanks again for all your help!
