Annie, I've been doing a very happy little dance!!!! all around the computer!!! And you being in Denver is amazing!
Martin w/ Wife Annie & 8 children are very well documented. I have addresses for them and have even been able to follow the children. Martin commuted between Denver & Leadville doing masonery work including one of the Hotels in Denver --- will find that address and maybe you'll know which one and if still there. Will look all this up and send up PM to see if it imspires any thoughts.
Daniel and family -- I have never found in Denver -- they got there in 1883 and left about 1900 so missed 1880 census and of course no 1890. Daniel worked at Appel & Company as a Tailor and in 1890 they lived @ 2912 Market.
Wife Annie T. (or F.) b. May 1862 (tho the date moves around a bit) in Scotland?? or Eng of Irish descent -- all that moves around too.
John J. b. March 1883
Mary E. "Maime" (Davenport) b. Jun 1888
Edward D b. Dec 1889
Pearle (Chamberlain) b. Dec 1892
Lillian F. b. 1894
Maud b. 1895
Mabel K. b. 1896/97
All above children born in Colorado
Lincoln R or B. born in Lincoln Nebraska in May 1899
Found Annie in NB with all children in 1900 census but NO
Daniel and No son John -- Annie is "head" of family.
Garnett (King) b. 1901 in KCMO (my grandmother)
Catherine (Caldwell, I think) b. 1908 in KCMO
Only census where I found Danile was 1910 with whole family in KCMO -- he was a Tailor/Merchant Annie a Shirtmaker?

Then he dies between 1910-1920 -- which my grandmother told me he died when she was a child)
Anna continues on in 1920/1930 in KCMO.
SO this is major to find part of Daniel history which has been a realy mystery --- now if I can find Annie!!!!!
I have looked for Daniel & Martin's nautralization in Colorado but found nothing.
Just saw your message on HOD carrier -----perfect!!!!!! Never hear that term! On of Martin's sons was also a bricklayer.
The 1883 date is from 1910 census -- Daniel and Annie in Jackson Co., Missouri (Kansas City, MO)
I'll get Martins info together and send shortly
Annie --- unbelieveable how one little piece brings everything together!
